While cycling along with the wind a biy can cover a distance of 30km in 3 hours and for returning back through the same distance he takes 5 hours find the speed of wind and speed of cycling in still air

Answer 1

Step-by-step explanation:

Let speed of boy is still wind be (x)

Sppeed of air be (y)

Speed=distance /time

First case

x + y =30/3=10.

x + y = 10. Eqn(1)

2nd case

x - y = 30/5=6

x - y =6. Eqn(2)

Solving both we get

x=8

y=2. And that is our ans

Answer 2
