In the Day VFR fuel calculation example, how many gallons are added as the 30-minute reserve?

Explanation:
The required 30-minute reserve is calculated as half an hour of the planned fuel burn. In this example, the aircraft’s burn rate is 13.3 gallons per hour. Half an hour is 0.5 hours, so the reserve equals 13.3 × 0.5 = 6.65 gallons. That’s why the correct amount added for the 30-minute reserve is 6.65 gallons. The other amounts don’t fit because they correspond to different burn rates or durations (for instance, a full hour at 13.3 gph would be 13.3 gallons, and 3.0 or 6.0 gallons do not equal half an hour at 13.3 gph).
