A tank has 240 gallons of fuel. It consumes fuel at 8 gallons per hour. How many hours until empty?

Explanation:
Time equals amount divided by rate. With 240 gallons and a consumption rate of 8 gallons per hour, divide 240 by 8 to get 30 hours. So the tank runs for 30 hours before empty. If you check the other options, they'd require different rates (20 hours would need 12 gph, 40 hours would need 6 gph, 60 hours would need 4 gph), which don’t match the given 8 gph.
