Maurice walked #6# miles on the treadmill in #3/2# hours. How many miles per hour did Maurice walk?

Answer 1

#4 " miles per hour"#

A rate is a comparison between two quantities with different units.

In this case we are asked for miles per hour which tells us that we need to divide the number of miles by the number of hours.

#6 div 3/2 = 6 xx2/3 = 4 " miles per hour"#

The same result would have been obtained from the formula for speed:

#speed = D/T#
