Hey,
Is there anyway to convert an allotted time to MPH in this problem on a BS2

F1 Car moves from point A to Point B within 66.8 ft. of track in a certain time

How would I convert the time into MPH if it is possible?

(IR's sense from Point A to Point B)

    MPH is miles per hour. A mile is 5280 feet and an hour is 60 * 60 = 3600 seconds. A mile per hour is 5280 feet / 3600 seconds = 1.467 feet / second. Now it's your turn ...

    Perhaps it would be clearer to say that speed is distance divided by time. If you want the speed in miles per hour, then (1) convert the distance into miles; (2) convert the time into hours; and (3) divide the distance by the time.

    Or more simply.... 45.54 / time = mph. 45.54 = 66.8*(3600/5280)
