Question

Mr. Sweeney's car can travel 195 miles on 10 gallons of gas. How far

can Mr. Sweeney travel if he buys 18 gallons of gas?
I

Answer 1

Miles travelled by the car on 10 gallons of gas = 195 miles

Miles travelled by the car in 1 gallon of gas = 195 ÷ 10 = 19.5 miles

Miles travelled by the car in 18 gallons of gas = 19.5 × 18 = 351 miles.

Answer 2

Miles in 10 gallons = 195

Miles in 1 gallon = 195/10 = 19.5

Miles in 18 gallons = 19.5 × 18 = 351 miles.
