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
