Answer:

20 km/hr

Step-by-step explanation:

x - speed of the cycle

x+10 - speed of the cycle in a direction of a wind

x-10 - speed of the cycle against the wind

Distance/Speed = Time

60/( x+10 ) + 60/ ( x-10) = 8

Solve the equation we get

x^2 -- 15x -- 100 = 0

x^2 -- 15x + 56.25 -- 56.25 -- 100 = 0

x (x--7.5)^2 = 156.25

x--7.5 =12.5

x = 20km/hr
