Question

\) In the morning, the bus driver traveled 3 miles every 4 minutes. In the afternoon, the bus driver traveled 4 miles every 5 minutes. What was the difference between her morning and afternoon traveling rates, in miles per hour? *

Answer 1

Explanation:

Speed = distance/time

In the morning, the bus driver traveled 3 miles every 4 minutes. It means that the speed at which the bus driver travelled in the morning is

3/4 = 0.75 miles per minute

In the afternoon, the bus driver traveled 4 miles every 5 minutes. It means that the speed at which the bus driver travelled in the afternoon is

4/5 = 0.8 miles per minute

the difference between her morning and afternoon traveling rates is

0.8 - 0.75 = 0.05 miles per minute

There are 60 minutes in 1 hour

Therefore

0.05 miles per minute = 0.05/60 = 0.00083 miles per hour
