Answer:
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
