flying to munich with a tailwind plane averaged 242 mph. on the return trip the plane only averaged 178 mph while flying back in

Romashka [77]

Answer:

The speed of wind is 32 mile per hour

The speed of plane is 210 mile per hour

Step-by-step explanation:

Given as :

The speed of plane with tailwind = 242 mph

The speed of the return trip = 178 mph

Let The speed of the wind = y mph

The speed of the plane = x mph

Now , According to question

The speed of plane with tailwind = x + y

Or, x + y = 242 mph .......1

and The speed of the return trip = 178 mph

or , x - y = 178 mph ........2

Solving both equations

( x + y ) + ( x - y ) = 242 + 178

Or, 2 x = 420

∴ x = $\frac{420}{2}$

I.e x = 210 mph

Put the value of x in eq 1

I.e x + y = 242 mph

or, 210 + y = 242

∴ y = 242 - 210

I.e y = 32 mph

Hence The speed of wind is 32 mile per hour

And The speed of plane is 210 mile per hour Answer
