Question

A vehicle has travelled 90 miles at 40mph

Answer 1

First let us calculate for the total time of the travel using the formula:

time = distance / velocity

time = 90 miles / 40 mph

time = 2.25 hours

 

Next, we calculate for the total gallons of fuel that is theoretically required:

theoretical amount needed = 90 miles / 24 mpg

theoretical amount needed = 3.75 gallons

 

The difference of the actual and theoretical amount is the amount which leaked:

amount leaked = 8 gallons – 3.75 gallons

amount leaked = 4.25 gallons

 

Therefore the amount of gallons leaked per hour is:

amount leaked per hour = 4.25 gallons / 2.25 hours

amount leaked per hour = 1.89 gallons / hr
