. A streamer 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/h, find the speed of the streamer in still water and the distance between two ports.
Speed of the stream in still water =1km/h
Let speed of the streamer =x km/h
Then the speed of downstream =(x+1)km/h
And the speed of upstream =(x−1)km/h
So, we have,
Distance between two ports =Speed downstream Time taken to cover the distance between two points
The speed of the streamer in still water is 11km\h and the distance between two ports is 60km.
