Question

A municipal transit system has 85 diesel buses that travel an average of 47,000 miles per year each. Because of the start and stop nature of a bus route, they only get an average of 5 MPG. If diesel costs $2.75 per gallon, how much is the annual fuel bill?

Answer 1

Total distance  per year:

$$85(47000)=3995000\ miles$$

The annual fuel volume:

$$\frac{3995000}{5}=799000\ gallons$$

The annual fuel bill:

$$(2.75)(799000)=\$ 2197250$$
