A boat can travel 333 miles on 37 gallons of gasoline. How much gasoline will it need to go 486 miles?
pochemuha
<h3>Answer:  54 gallons</h3>

Work Shown:

(distance)/(gallons used) = (distance)/(gallons used)

(333 miles)/(37 gallons) = (486 miles)/(x gallons)

333/37 = 486/x

333x = 37*486 .... cross multiplication

333x = 17,982

x = (17,982)/333

x = 54 gallons

You need 54 gallons to travel 486 miles.
