Best Answer

About 25.5mph assuming my math is correct: 5280ft/330=16 16x9.68=2min35sec 60mph/2.6min=25.5mph

The above answer is incorrect. This would be true if it was a constant velocity, but because the runners are starting from a stop you need to factor in acceleration. But again we run into a problem because the acceleration is not constant so calculating the final velocity would be a bit tricky. A time of 9.68 the runner would probably be going close to 30mph.

Answer:

9.69 secs for 100 meter sprint. That is 96.9 seconds for 1 kilometer; 3600 seconds in an hour, so 3600/96.9 = 37.15 km/hr.

37.15 kilometers per hour (km/hr) x 0.621 = 23.0702 miles per hour (mph).

Converting 100 meters into yards... 100 meters = 109 yards Usain Bolt ran "109 yards" in 9.69 seconds... 109 / 9.69 = 11.2 yards per second The "mythical" 40-yard dash time... 40 / 11.2 = 3.63 seconds!!!!! Simply astonishing!

22.68 mph

You transfer meters to yards. 100 meters = 108.3333 yards...then feet. 108.333*3 = 325

So you travel 325 feet in 100 meters, which is 6.155% of a mile.

Then you turn the seconds into hours. 3600 seconds in an hour, divided by 9.77= .2714% of an hour.

Now you have it in correct units, so you put it in miles per hour. So 6.155/.2714 = 22.68 mph

100 meters in 9.7 seconds equates to a pace of 23.06 miles per hour.

23.5 MPH or 37.6 kph If your asking how fast Usain Bolt was going, he was going 27.3 MPH because he had to excellerate from 0 to 27.3 MPH. 23.5 is is average speed.

Your average speed for the race is 20.87 miles per hour.

About 24 miles per hour.
