A school bus uses 3/4 of a tank to drive back and fourth to school in a week with 5 school days. How much gas does the bus use to drive back and fourth to school in a week with 4 school days?

Answer 1

Explanation:

17 gallons of gas drive back and fourth

Answer 2

3/5 of a tank

Explanation:

You can use a proportion.

3/4 tank is to 5 days as x is to 4 days

(3/4)/5 = x/4

Cross multiply.

5x = 3/4 * 4

5x = 3

x = 3/5

Answer: 3/5 of a tank
