If you are riding your bike west to your friend’s house, and you ride the 1.25 miles in 5 minutes, what is your velocity, in miles per hour?

Explanation:

distance = 1.25 mile

time traveled = 5 min.

find velocity in miles / hour

solution:

use the formula: velocity = distance / time

velocity =     1.25 mile     x 60 min  

                     5 min            1 hour

velocity = 15 miles / hour
