ms. walters drove 160 miles on 5 gallons of gas. how many gallons of gas will she need to travel 256 miles and why and an example

Question

igreen · Answer

First find the amount of miles she travels with 1 gallon.

160 / 5 = 32 miles per gallon.

Since she travels 32 miles per gallon, we can divide that with 256:

256 / 32 = ? @noterdame13

The more the miles...the more the gallons

160 miles.......5 Gallons
256 miles.........of course more than 5 Gallons?

This is called direct proportion,Cross multiply and get the answer.
