Answer:
The velocity of jet in still air is
and velocity of wind is
.
Step-by-step explanation:
Let x be the rate of the jet in still air and y be the rate of the wind.
Given:
Velocity against wind, a jet travels 2160 miles in 3 hours.
Velocity against wind 
Flying with the wind, same jet travels 6000 miles in 6 hours.
Flying with the wind 
As such its velocity against wind is 
and with wind is
therefore
------------(1)
---------------(2)
Adding equation 1 and 2.



Put x value in equation 2



Hence velocity of jet in still air is
and velocity of wind is
.
It's an equilateral triangle, therefore
AB = BC = BA
We have the equation:


<h3>Answer: BC = 3</h3>
