Flying against the wind, an airplane travels 3800 kilometers in 4 hours. Flying with the wind, the same plane travels 3750 kilometers in 3 hours. What is the rate of the plane in still air and what is the rate of the wind?

---- velocity of wind

--- velocity of airplane

Step-by-step explanation:

Given

velocity of airplane

velocity of wind

Flying with the wind, the distance (d) is:

Where d and t are distance travel and time spent with the wind

So:

Divide by 3

Flying against the wind, the distance (d) is:

Where d and t are distance travel and time against with the wind

So:

Divide by 4
