Ajet airplane is traveling west from austin, texas to miami, florida. it has an average speed with no wind of 600 mph. an observer on the ground records the airplane of having a speed of 580 mph. what speed and direction is the wind moving?

20 mph due East from Austin

Explanation:

The relative speed of A with respect to B is given by:

It is given that average speed of jet airplane travelling west from Texas to Miami is 600 mph.

The speed of the airplane as measured by the observer on the ground:

This is the relative speed  of the airplane with respect to wind measured by the observer on the ground.

We need to find the speed of the wind:

As the relative speed is slower, it means the wind is blowing in the opposite direction.

Thus, the speed and direction of blowing wind is 20 mph due East from Austin

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
