Answer:
Velocity in still air is = 960 miles per hour
Velocity of wind = 230 miles per hour.
Step-by-step explanation:
The velocity when flying against the wind = 2920 / 4 = 730 miles per hour.
The velocity when flying with the wind = 7140 / 6 = 1190
Let the rate of jet in still Air = x
Let the rate of jet in wind = y
Therefore, velocity against wind = x-y and wind = x + y
x - y = 730
x + y = 1190
Add both equation, 2x = 1920
x = 960
Now find the value of “y” = 1190 – 960 = 230
Thus, velocity in still air is = 960 miles per hour
Velocity of wind = 230 miles per hour.
