Question

Neveah’s car can travel 480 miles on 12 gallons of gas. Find how many gallons her car can needs to travel 680 miles.

Answer 1

17 gallons

Explanation:

We can write this as a ratio

480 miles 680 miles

--------------- = ---------------

12 gallons x gallons

Using cross products

480*x = 680*12

Divide each side by 480

480*x = 680*12

480x/480 = 680*12/480

x =17
