a steamer goes downstream from one point to another in 20 hours. while going upstream it covers same distance in 32 hours. if the speed of the stream is 6 km/h, find the speed of the steamer in still water and the distance between the 2 points
Answers
Answer:
26 km/hr
Let the speed of the streamer be x km/hr
Speed of Stream = 2 km/hr
It is given that while going downstream, the streamer takes 6 hours to cover the distance between two ports.
Speed of the streamer downstream = (x+2) km/hr
Distance Covered in 1 hour = (x+2) km
Distance covered in 6 hours =6(x+2) km
Distance between 2 ports = 6(x+2) km ....(i)
It is given that while going,upstream the streamer takes 7 hours to cover the distance.
Speed of Streamer Upstream = (x-2)km/hr
Distance covered in 1 hr = (x-2)
Distance covered in 7 hrs = 7(x-2) km
Distance between two ports in this case = 7(x-2) km ....(ii)
The distance between two ports is the same.
The speed of the streamer in still water = 26km/hr
