Question

Julie’s family took a 4-day trip. Julie’s mother wrote an equation to calculate their gas mileage, m, in miles per gallon. Let d = the number of total miles driven on the trip. Let g = the total number of gallons of gas used for the trip.

=



What was the gas mileage for the 4-day trip?

Answer 1

`m = 26`

Explanation:

Given

Required

Determine the gas mileage for the trip

First, we calculate the miles driven

`Miles = 476 + 439 + 382 + 263`

`Miles = 1560` --- d

Next, we calculate the amount of gas used

`Gas = 15.0 + 13.5 + 15.4 + 16.1`

`Gas = 60.0` ---- g

The gas mileage is then calculated as:

`m = (d)/(g)`

`m = (1560)/(60)`

`m = 26`

Hence, the gas mileage is 26 miles per gallon
