You don't have any planned flights for the next few weeks.
The lunch stop's gas is the same price as as at your home field.
The lunch stop's runway is 5,000 at sea level.
The flight time to lunch is 30mins

How many mins of fuel do you add to your tanks for the flight?

Here is the summery in the form of:
in the plane + personal min + trip + extra

30 + top
