A mile contains 1760 yards. Therefore, 40 yd/1760(yd/mi) = 0.0227 miles. An hour contains 60 minutes of 60 seconds each. Therefore, 6.5 seconds = 6.5/(60 X 60) = 0.00181 hour. 0.0227 miles/0.00181 = 13 mph, to the justified number of significant digits.
Improve your time-related sense of time! 52 miles per second equals 187200 mph, anyway (if that's your question!)
6.316 mph
3600 seconds.
MPH equals the miles driven, divided by the time it takes to drive those miles (units of time is hours, or minutes divided by 60).
3 mph = 4.8 km per hour
I was thinking the same thing but I found a solution:Basically 1 second= 0.00027778 hours.13mph- 0.06214(calculation of length of 100m)÷(0.00027778X13(your speed))This equals=17.21 seconds as your 100m dash time.It might look complicated but I simplified it.

19.2839 mph
speeds like mph are distance divided by time. So divide 100 meters by the dash time to get a speed. Then convert units to miles per hour. Or convert before you divide, meters to miles and dash time to hours.
A 5.7 second 40 yard dash is roughly equivalent to maintaining a pace of about 11 mph.
30 mph at that rate.

150 mph = 241.4016 kph
3600 seconds.
99 feet per second = 67.5 mph
40 yrds. equals 120 ft. divide 120 ft. by 5.8 sec. equals 20.69 fps. Multiply 3600 seconds in an hour by 20.69 fps. equals 74,484 ft per hr. Now divide 74,484 fph by 5280 ft in a mile. Your speed is 14.10 MPH.
