This is ratio math.A passenger car will go 420 miles on 17.5 gallons in city driving. What is the rate in miles per gallon? The rate is... mpg

Sagot :

We are given two variables, distance and volume of gas required to reach the distance.

We are then asked to find the rate of consumption in miles per gallon.

The approach is simply to divide distance by the volume to get the rate per unit gallon.

[tex]\begin{gathered} \frac{420}{17.5}\cdot\frac{\text{miles}}{\text{gallons}} \\ 24\text{ miles per gallon.} \end{gathered}[/tex]

This means that for each gallon consumed, 24 miles are covered.

24 mpg
