Problem:How much fuel is consumedin 6 hours at a fuel consumption rate of 250
gallons per hour?

of the inside scale. The 6:00 is aligned with 15, and the answer is 1500
gallons.
4. Fuel consumption rate calculation
Problem:If 120 gallons of fuel are consumed in 30 minutes’ flying time, what is the
