Question

A man is cycling in a windy place he travels 12 km in against the direction of wind in doing so he took the same time as he took while going 28 km in the direction of the wind if the man is cycling at the rate of 12 km / hour find the speed of the wind hint

Answer 1

the wind speed will be 32 km/h because the cycle prevents the 1/2 speed of the wind and accepts the other 1/2 of the wind to the speed....

Hope helps you

Answer 2

Answer:

Speed of the wind is 4 km/hr.

Step-by-step explanation:

Given:

Distance traveled against the wind = 12 km

Distance traveled in the direct of wind = 24 km

In both cases time taken is same.

Normal Speed of the cycling = 12 km/hr

To find: Speed of wind.

let x be the speed of wind.

According to the Question,

$\frac{12}{12-x}=\frac{24}{x+12}$

$12(x+12)=24(12-x)$

12x + 144 = 288 - 24x

12x + 24x = 288 - 144

36x = 144

x = 4

Therefore, Speed of the wind is 4 km/hr.
