Answer: The airplane can fly 124.8 miles in 1 hour.

Step-by-step explanation: Given that a small airplane flew 104 miles in 50

minutes.

We are to find the number of miles that the airplane can fly in one hour.

We will be using the UNITARY method to solve the given problem.

We have

$60~\textup{minutes}=1~\textup{hour}\\\\\Rightarrow 50~\textup{minutes}=(1)/(60)*50=(5)/(6)~\textup{hour}.$

In
(5)/(6) hours, number of miles flew by the airplane = 104 miles.

So, in 1 hour, number of miles flew by the airplane is

(104)/((5)/(6))=(624)/(5)=124.8.

Thus, the airplane can fly 124.8 miles in 1 hour.
