Step-by-step 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
