Question

The city to highway fuel economy on the new car I just bought is 25:32. Yesterday, I drove 123 miles in the city. How many MORE miles could I have driven on the highway? A) 34.44 miles B) 96.09 miles C) 157.44 miles D) 861 miles

Answer 1

Answer:

A)34.44

Step-by-step explanation:

To find how many MORE miles you could've driven on the highway, we first need to find the number of miles on the highway is compared to 123 miles in the city.

Let x = number of miles in the highway

$\dfrac{25}{32}=\dfrac{123}{x}$

$\dfrac{25x}{25}=\dfrac{3936}{25}$

x = 157.44

So now that we know the value of x, we then subtract it to the number of miles in the city to find how much MORE you could've driven.

Total Miles = 157.44 - 123

Total Miles = 34.44
