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.

To convert from square yards to square miles, multiply by 3.228E-07.
1 miles = 5280/3 yards = 1760 yards. 50 yards / 1760 yards/mile ~= 0.02841 miles 6.6 seconds / 3600 seconds/hour ~= 0.001833 hours 0.02841 miles / 0.001833 hours ~= 15.5 miles per hour
1 yard = 0.000568181818 miles
3.5 seconds in the 30 yard dash equals 17.53 miles per hour.
Running a 40-yard dash in 4.2 seconds equates to a pace of 19.48 miles per hour.
13.4 miles per hour.
Hines Ward's 40 yard time is 4.55 seconds.
The sprinter's speed is 22.53 miles per hour.
A pace of 18.6 mph is required.
They can sprint up to 45 to 50 miles per hour.
4.5 seconds in the 40-yard dash is a pace of 18.18 mph
(50 yards/6.6 seconds) x (3,600 seconds/hour) / (1,760 yards/mile) = 15.496 miles per hour (rounded)
You need only to convert 1 yard to meters or centimeters. 1 yard is 0.9144 meters or 91.44 centimeters. Your conversion is 0.9144 meters per hour or 91.44 centimeters per hour.
First lets convert mph (miles per hour) to yard per hour1 miles per hour = 1760 yard per hourso 10 miles per hour = 17600 yard per hourNow lets divide 100yards/17600yard per hour100/17600 = 0.00568 hourLets convert hours to minutes1 hour = 60 minutes0.00568 x 60 = 0.3408 minuteslets convert minutes to seconds1 minute = 60 seconds0.3408 x 60 = 20.448It takes 20.448 seconds to cover 100 yards at 10mph
You can't. It would be like extrapolating a marathon time from a mile time.
