Question

While cycling along the wind; A boy can cover distance of 30 km in 3 hours and for returning back through the same distance he takes 5 hours. Find the speed of wind and the speed of cycling in air.

Answer 1

According to question

Let speed of Cyclic in Still Air be u
and Speed of Air be v

Thus,
While cycling long the wind

Speed = v+ u
and given that x = 30 Km
when   t = 3 hrs

So,             v+ u = 30/t
                   v + u = 30 / 3 = 10
So              v + u = 10

Similarly 
while cycling in opposite direction

Speed = v - u

So
     v - u = 30/5
       v - u = 6

Thus equating the above two equations

          2v = 16
            v = 8 
So       u = 2

Answer 2

Answer:

HOPE IT HELPS

Step-by-step explanation:

so here I have taken speed of wind as x and speed of cycle as y but you can take it either wind as y or cycle as x............. It won't be wrong
