Question

streamer goes downstream and covers the distance between two points in 5 hours while its cover the same distance upstream in 6 hours in the speed of the stream is 1 km per hour find the speed of the steamer in still water and the distance between two ports

Answer 1

Let the steamer speed will be x.

Downstream speed = (x+1)
Distance between the points = 5(x+1)    ---------- (1)

Upstream speed = (x-1)
Distance between the points = 6(x-1)     ------------ (2)

On solving (1) and (2), we get

5(x+1) = 6(x-1)

5x+5 = 6x - 6

x = 11.


Hope this helps!

Answer 2

Answer:

11.

Step-by-step explanation:

Let the steamer speed will be x.

Downstream speed = (x+1)

Distance between the points = 5(x+1)-- (1)

Upstream speed = (x-1)

Distance between the points = 6(x-1)--- (2)

On solving (1) and (2), we get

5(x+1) = 6(x-1)

5x+5 = 6x - 6

x = 11.
