the fastest 40 yard dash is 4.24 seconds but it would be easier to ask your college alg teacher The 4.24 40 is equivalent to about 19.23 mph, computed as follows: one hour equals 3600 seconds. Divide the 3600 by the 4.24 to get 849 (theoretical) times that 40 would be run in one hour. Multiply the 849 times 120 feet to get total feet traveled in that hour (101,887). Divide the 101,887 by the number of feet in a mile (5,280) to get 19.23. Keep in mind that is the average speed over the 40 so when the combine shows speeds in excess of that, they are calculating the highest speed during the run, with zero being the start and the max near the end.
I do not know. But when i was twelve, I ran a 100meter dash in about 12, 13 seconds. Is that good?
