Question 427726
Jake has a Car with an 8-Gallon fuel tank.
 Jake fills his tank with gas and then drives 60 miles to a friend's house.
 when he gets to his friend's house he has 6 gallons left in his fuel tank.
 how many miles can jake travel on a full tank of gas?
:
First find out how many miles he gets from 1 gal. 
If he travels 60 mi and uses 2 gal, (6 gal left) then {{{60/2}}} = 30 mi on 1 gal of gas.
then on a full tank of 8 gal he can go; 8 * 30 = 240 mi
