Question

Joe filled up his car’s gas tank. After travelling 165 km, 3 8 of the gas in the tank was used. At this rate, approximately how much farther can the car travel before its fuel tank is completely empty?

Answer 1

275 km

Explanation:

It has 1 - 3/8 = 5/8 of a tank left.

3/8 of a gallon gives 165 km

So 1 gallon gives 165 / 3/8 = 165 * 8/3 km

5/8 gallon gives 168 * 8/3 * 5/8 km

= 165 * 5/3

= 275 km (answer)
