Question

Given that a new fuel-efficient cars can drive 55 miles per gallon, how far can a car drive with nine gallons?

6.11 miles


455 miles


495 miles


540 miles



I think it is C, correct?

Answer 1

Set this up as a proportion with miles on the top and gallons on the bottom.
`(m)/(g): (55)/(1)= (x)/(9)`. Cross multiply to get that the car can go 495 miles on 9 gallons of gas.
