How many gallons of fuel are needed, including day VFR reserves, for a cruise time of 4 hours and 36 minutes?

To determine how many gallons of fuel are required for a cruise time of 4 hours and 36 minutes, it is essential to account for the planned flight duration and any additional fuel reserves mandated for VFR (Visual Flight Rules) operations.

Firstly, convert the cruise time into hours. Four hours and 36 minutes is equivalent to 4.6 hours when you convert the minutes into a decimal (36 minutes is 0.6 of an hour).

Next, consider the aircraft's fuel consumption rate, which is usually provided in gallons per hour. To find the total fuel needed, multiply the cruise time in hours by the aircraft's burn rate. For example, if the aircraft consumes 15 gallons per hour, the fuel needed for 4.6 hours of flying would be calculated as follows:

15 gallons/hour * 4.6 hours = 69 gallons.

Day VFR reserves typically require an additional 30 minutes of fuel, which should also be added to the total. Thirty minutes accounts for one-half hour, and if we continue using a consumption rate of 15 gallons per hour, we would calculate the extra needed fuel:

15 gallons/hour * 0.5 hours = 7.5 gallons.

Adding this reserve to
