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.
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!
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.
Your average speed for the race is 20.87 miles per hour.
About 24 miles per hour.
A 10.49-second 100-meter dash equates to an average speed of 21.32 miles per hour.
The sprinter's speed is 22.53 miles per hour.
3.5 seconds in the 30 yard dash equals 17.53 miles per hour.
7.2 seconds in the 55 meters converts to 4.788 seconds in the 40-yard dash.
He attended Evander Childs High School in the Bronx NY
Based on combine results from 2000-2017, the average speed of a Strong Safety in the 40 yard dash is 4.55 seconds.
100m/40s or 2.5 metres per second.
