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!)

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

22 mph = 9,78 m/s 100 m dash time = 100/9,78 = 10,22 s Answer: the time would be 10,22 s, with a average velocity of 22 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.
121 kph = 75.18 mph
13.4 miles per hour.
30 mph at that rate.
