Expert Solution

Step 1

Given data

The distance between the two cities is A and B is d = 792 miles.

The time interval taken by the flight in a forward trip is t_f = 2 hours.

The time interval taken by the flight in return trip is t_r = 1.5 hours.

Let us consider the velocity of the plane is x and the velocity of wind is y.

From the relationship of distance and time, the equation between x and y in forward flight is calculated as,

$\begin{array}{rcl} d & = & v_{r e v} \times t \\ 792 miles & = & (x - y) \times 2 hours \\ x - y & = & 396 \\ x & = & 396 + y . . . . . . . . . . . (1) \end{array}$
