Billy ran 100 miles in 16 hours.
a) what was Billy's average speed in miles per hour?
I answered 6.25 mph
To get mi/hr, divide the miles by the hours.
100/16 = 6.25
==========================
b) how long did it take billy to run a mile?
To get hours/mile, divide the hours by the miles.
16/100 = 0.16 hours.
----------------
No units were spec'd, but you can change that to minutes or seconds (or weeks or months).
0.16 hr * 60 min/hr = 9.6 minutes.
