The read transition time for one user bit off of a ROM disk in the fastest DVD drives on the market today is about 8.33 nanoseconds or 120 megabits/second. Typically, you will see DVD speeds in groups of three numbers, for example: 2x1x8x. These speeds refer to the following functions of the DVD drive: Writing to 'R' media x Writing to 'RW' media x Reading 'ROM' media (R = Recordable, RW = ReWritable, and ROM = Read Only Memory.)  1X DVD transfer rate is defined as 1.25 megabytes/second (MB/s).  Today’s peak performance DVD+R/RW drives are rated at 4x2.4x12x or 5 MB/s - 3 MB/s - 15 MB/s.

Common snail - Helix aspersa
Snail Image 0.0085 km/hour 0.2777777778 0.0023611111 Speed of a Snail "The fastest speed achieved by a snail in the Guinness Gastropod Championship, held over a 13-inch (330-millimetre) course in the O'Conor Don pub in central London, is only 0.0085 kilometres per hour. This record is held by a mollusc called Archie, which took 2 minutes and 20 seconds to cover the course." "Well, the fastest snail that I've ever had covered a two foot course, which is a standard course for a snail race … in some three minutes flat. Now any mathematicians listening to the program will realize straight away that works out at 132 hours to travel a full mile." http://news.bbc.co.uk/2/hi/uk_news/558515.stm
Ken Warby's Spirit-1
Spirit of Australia - Fast Boat 317.6 miles/hour 0.44704 141.9799040000 World's Fastest Boat The World Water Speed record, like the air speed record, is decades old. Australian Ken Warby set the record in 1978 when he averaged 317.60 mph in a 27-foot jet-powered hydroplane called "Spirit of Australia." The official speed test, which consists of two back-to-back runs over a one-kilometer straight-away, took place on Blowering Dam in New South Wales, Australia. And where did Warby design and build this hydraulic masterpiece? Underneath a tree in the back yard of a house he was renting in suburban Sydney. "There was a canvas sheet I used to throw over it when it rained," he told the press. http://www.pbs.org/wgbh/nova/barrier/machines.html
Shinkansen - Japanese Bullet Train 581 km/hour 0.2777777778 161.3888889018 Speed of Japanese Bullet Train The Tokaido Shinkansen, connecting Tokyo, Nagoya, Kyoto and Osaka, was inaugurated in the year 1964 as the first shinkansen line and the world's first high speed train. In 1964 the trains already run with speeds of about 200 km/h. Nowadays (2007) they reach speeds of over 300 km/h in typical operation. On December 2, 2003, a three-car train set attained a maximum speed of 581 km/h in a manned vehicle run.

Thrust SSC - Fastest Car 763.035 miles/hour 0.44704 341.1071664000 World's Fastest Car The battle to break the sound barrier on land was won exactly 50 years after Chuck Yeager broke it in the air ... On October 13, 1997, a British jet car called ThrustSSC made two supersonic passes across Nevada's Black Rock desert at 760.135 m.p.h. and 763.168 m.p.h. It took British fighter pilot Andy Green exactly 61 minutes to make the two runs, narrowly disqualifying him for an official land speed record, which requires that the two runs be made within 60 minutes. Two days later the first ever supersonic World Land Speed Record was made official when the ThrustSSC completed two runs within an hour at an average speed of 763.035mph.  http://www.pbs.org/wgbh/nova/barrier/machines.html http://www.bluebird-electric.net/land_speed_record_history.htm
22 Caliber Bullets 1400 ft/sec. 0.3048 426.7200000000 Speed of a Bullet - 22 Caliber There are a variety of different types of .22 Long Rifle (or ".22 LR") loads. They are often divided into 4 distinct categories: 1) subsonic velocity (also includes "target" or "match" loads at velocities below 1100 feet per second nominal velocity);   2) standard velocity (1120 -1135 feet per second nominal velocity); 3) high velocity (1200-1310 feet per second nominal velocity)   http://en.wikipedia.org/wiki/.22_Long_Rifle Units Guy- Fort Collins, CO  USA http://www.pyramydair.com/site/articles/velocity/ http://hypertextbook.com/facts/1999/MariaPereyra.shtml
F-16 or F16 Image 2124 km/hour 0.2777777778 590.0000000472 Speed of a F-16 Jet Aircraft The F-16 Fighting Falcon is a multirole jet fighter aircraft developed by General Dynamics and Lockheed Martin for the United States Air Force. Designed as a lightweight fighter, it evolved into a successful multirole aircraft. The Falcon's versatility is a paramount reason it was a success on the export market, serving 24 countries. The F-16 is the largest Western fighter program with over 4,000 aircraft built since production started in 1976. Though no longer produced for the US Air Force, it is still produced for export.The maximum speed of the F-16 is Mach 2 (1,320 mph, 2,124 km/h) at altitude.

SR-71 in flight
Lockheed SR-71 Blackbird 2200 miles/hour 0.44704 983.4880000000 World's Fastest Airplane The Lockheed SR-71 Blackbird is, to date (2007), the fastest airplane ever to streak across the sky, even though it's more than 30 years old. Capable of speeds over 2200 miles per hour -- that's more than three times the speed of sound -- the SR-71 can fly at altitudes above 80,000 feet. What does it feel like to travel at Mach 3, 15 miles above the earth? Pilots report that, with no view out the window, there's an eerie sensation of motionlessness when cruising in the Blackbird. http://www.pbs.org/wgbh/nova/barrier/machines.html
Planet Earth from space 108,000 km/hour 0.2777777778 30000.0000024000 Speed of the Planet Earth Many dream of traveling in space and viewing the wonders of the universe. In reality all of us are space travelers. Our spaceship is the planet Earth, traveling at the speed of 108,000 kilometers (67,000 miles) an hour around the sun. http://www.solarviews.com/eng/earth.htm
