Question

It took Walter's 15 minutes to bike to his friend Sonya's house 1/2 mile away.What was Walter's biking rate in mile per hour?

Answer 1

2 miles per hour

Explanation:

Remember that

`1\ hour=60\ minutes`

To convert minutes to hours divide by 60

To find out Walter's biking rate, divide the total distance by the total time

so

`(1)/(2) :15`

convert minutes to hours

`(1)/(2) :(15)/(60)=(60)/(30)=2\ (miles)/(hour)`
