Noah bought a new car. It gets 21.7 miles per gallon of gas on the highway. His gas tank is able to hold 14 gallons of gas. How many miles can know what travel on the highway on one tank of gas?

Noah can travel 30.38 miles on the highway on one tank of gas.

Step-by-step explanation:

One gallon of gas covers = 2.17 miles

The gas tank capacity of the new car = 14 gallons

So, the total distance traveled by 14 gallons

= 2.17 miles x 14 gallons

= 30.38 miles/gallon

or, the distance traveled by full tank = 30.38 miles/gallon

Hence, Noah can travel 30.38 miles on the highway on one tank of gas.
