A test of a hybrid car resulted in 4,840 miles driven using 88 gallons of gas. At this rate, how many gallons of gas will this vehicle
need to travel 1,155 miles?

21 gallons

Step-by-step explanation:

4,840 miles = 88 gallons

=> 1155 miles = x gallons

=> Cross-multiply

=> 4840 * x = 1155 * 88

=> 4840x = 101640

=> 4840x/4840 = 101640/4840

=> x = 21

The car can travel 1,155 miles using 21 gallons.
