A truck drives 120 miles and uses 5 gallons of gasoline. How far could the truck drive with 7 gallons of
gasoline? (1 point)
168 miles
840 miles
O 24 miles
86 miles
To find out how far the truck could drive with 7 gallons of gasoline, we can set up a proportion:
120 miles / 5 gallons = x miles / 7 gallons
Cross-multiplying to solve for x:
5x = 840
Dividing both sides by 5:
x = 840 / 5
x = 168
Therefore, the truck could drive 168 miles with 7 gallons of gasoline.
