Question

A Toyota Prius can drive 70 miles on two gallons of gas. At this rate, how far can the Prius travel on 13 gallons of gas? Include your units.

Answer 1

460 miles

Explanation:

Since it is a ratio problem, you see that the prius drives 70 miles on 2 gallons of gas which gives you 70:2 or 70/2.

You also set up the other ratio as a fraction with the unknown value as x --> x/13.

now, you cross multiply

70/2=x/13

70*13=910

910/2=460

460 miles

Answer 2

455 miles

Explanation:

Distance Prius can travel with one gallon of gas:

70/2

= 35 miles

Distance Prius can travel with 13 gallons of gas:

35*13

= 455 miles
