Question

If you run 120 feet in 4. 8 seconds how many miles per hour would you be running?

Answer 1

17 miles per hours

To solve the problem:

`(120 feet )/ (4.8 seconds) = 25 feet per second`

first figure out the number of feet per second.

`(25 feet per second)/ (5280 feet) = 0.00473484848... mps`

next use the feet per second divided by the number of feet in a mile

`(0.00473484848... mps)*(3600 seconds) = 17.04545454... mph`

and to get the answer, take the mile per second and times that by the length of time (in this case number of seconds in an hour.)
