If you burn 5 gallons per hour and fly for 4.25 hours, how many gallons are consumed?

Explanation:
Fuel use is found by multiplying the burn rate by the time of flight. At 5 gallons per hour for 4.25 hours, the total is 5 × 4.25 = 21.25 gallons. You can see this by breaking it down: 4 hours at 5 gallons per hour is 20 gallons, plus 0.25 hour at the same rate is 5 × 0.25 = 1.25 gallons, totaling 21.25 gallons. This matches the 21.25 gallons option. The other numbers would require a different time or burn rate.
