Question

The tank of a small airplane holds 48 gallons of fuel. Seven gallons will be used for takeoff and landing. While in the air, the plane will consume an average of 10 gallons of fuel per hour. What is the maximum number of hours the plane can remain in the air

Answer 1

Answer:

4 hrs

Step-by-step explanation:

Total gallons that are in the plane = 48

Used for takeoff and landing = 7.

Remaining that is left to be used while in air = 48-7

                                                                          = 41.

maximum number of hours the plane can remain in the air= Maximum of    (  $\frac{41}{10}$ )

So maximum of 4 hours.
