Question

My car can travel 300 miles on one tank of gas. My car can hold 20 gallons of gas. Calculate the unit rate and explain what your answer represnts in a complete sentence.

Answer 1

Unit rate = 15 miles/gallon

The unit rate represent that the car travels 15 miles in 1 gallon (unit) of gas.

Explanation:

Capacity of car (gas tank) to hold gas = 20 gallons

Distance traveled by car in one full tank = 300 miles

To find unit rate, we will use unitary method.

In 20 gallons of gas = the car can travel 300 miles

∴ In one gallon of gas car will travel =
`(300\ miles)/(20\ gallons)=15\ miles`

Unit rate = 15 miles/gallon (Answer)

This unit rate represent the number of miles traveled by the car in 1 gallon(unit) of gas.
