A steamer goes downstream and covers the distance between two ports in 5 hours while it covers the same distance upstream in 6 hours. If the speed of the stream is 1 km/hr, find the speed of the steamer in still water.
(A) 12 km/hr (B) 11 km/hr
(C) 13 km/hr (D) 14 km/hr
It's urgent

Here is your answer...⤵
Let the steamer speed will be x
Downstream speed = (x + 1)
Distance between the points = 5(x-1)⋯(i)
Upstream speed = (x-1)
Distance between the points = 6(x-1)⋯(ii)
on solving (i) and (ii)
5(x + 1) = 6(x-1)
5x + 5 = 6x-6
5x-6x = -6-5
-x = -11
x = 1
∴The steamer speed will be 11km/hr
