Question

A certain car can drive 119 miles on a tank of 5 gallons. how many gallons are needed to drive 1190 miles? Round to the nearest tenth of a gallon.

Answer 1

We know that the car can travel 119 miles per 5 gallons, to determine the miles per gallon we divide this distance by the tank capacity:

`(119)/(5)=23.8`

To determine how much gas we need for a 1190 mile drive we divide the distance by the mileage per gallon, then we have:

`(1190)/(23.8)=50`

Therefore we need 50 gallons
