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

Answer:

$m = 26$

Step-by-step explanation:

Given

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:

$m = \frac{d}{g}$

$m = \frac{1560}{60}$

$m = 26$

Hence, the gas mileage is 26 miles per gallon
