If you have 25 gallons and burn 2.5 gallons per hour, how many hours endurance?

Explanation:
Endurance is how long the fuel on board will last, found by dividing the amount of fuel by the burn rate. With 25 gallons available and a burn rate of 2.5 gallons per hour, 25 ÷ 2.5 equals 10 hours. A quick mental-math check: 2.5 times 10 is 25, so the burn rate fits into the total fuel ten times. The units cancel to hours, giving ten hours of endurance. In practice, pilots also consider reserves, but for the pure calculation this is the result.
