A car can travel 340 miles on 10 gallons of gasoline. How much gasoline will it need to go 510 miles?

The answer to your question is 15 gallons

Step-by-step explanation:

Data

distance 1 = 340 mi

volume 1 = 10 gal

distance 2 = 510 mi

volume 2 = ?

Process

To solve this problem we know that there is a direct proportion between the distance traveled and the gasoline used. The more distance traveled, the more gasoline used.

                             340 mi 10 gal

                              510 mi    x

                              x = (510 x 10)/340

                              x = 5100/340

                              x = 15 gallons

560

hope this : )
