The gasoline a vehicle uses varies directly to the distance the vehicle travels. A car uses 10 gallons of gasoline to travel 210 miles. How many gallons will the car use to travel 294 miles

Answer :

Answer:Let amount of gallons of gas be G

Then: 10/G = 210/ 294

10 / G = 5/7

Simplifying right-side of equation by dividing it by 42/42

5G = 70 ------ Cross-multiplying

G or amount of gas = 70/ 5, or 14 gallons
