Question

Kim used 28 gallons of fuel to go 575 miles. if she needs to go 1400 miles, about how much fuel will she use?

Answer 1

To find how many gallons for 1400 miles set up a ratio:

28 gallons / 575 miles = X gallons / 1400 miles

Cross multiply.

1400 x 28 = 39,200

Divide that by 575 to get X

x = 39,200 / 575 = 68.17 gallons. Round answer as needed.
