fuel tanks can install 20 gallons, each gallon can run 30~40 miles (inclusive) A car actually runs 480 miles. What is the maximum amount of oil that can be left in the tank?
likewhoa,
Tanker can store = 20 gallons
Maximum oil reqd to travel = 480/40 = 12 gallons
So remaining amount of oil = (20 - 12) = 8 gallons.
