Question

Juan drove his car on a vacation trip. His odometer Read 1460.3 when he began and 1830.2 at the end. If he used 20 gallons of gas how many miles per gallon did he get

Answer 1

Juan got 18.50 miles per gallon.

Explanation:

We are given the following in the question:

Odometer in the beginning of trip = 1460.3 miles

Odometer at the end of trip = 1830.2

Gallons of gas used for trip = 20 gallons

Distance of trip =

= Odometer at the end of trip - Odometer in the beginning of trip

`=1830.2-1460.3\\=369.9\text{ miles}`

Thus, the trip was of 369.9 miles.

Miles per gallon =

`=\frac{\text{Distance cover in trip}}{\text{Gallons of gas used}}\\\\=(369.9)/(20)\\\\=18.495\approx 18.50\text{ miles per gallon}`

Thus, Juan got 18.50 miles per gallon.
