Question

A steamer goes downstream and covers the distance between two places 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.​

Answer 1

Answer:

Given

Speed of the stream in still water =1km/h

Let speed of the streamer =xkm/h

Speed downstream =(x+1)km/h

Speed upstream =(x−1)km/h

According to the given condition,

(x+1)×5=(x−1)×6

5x+5=6x−6

x=11

Hence , Speed of streamer in still water is 11km/h and

Distance between two ports =(11+1)×5=60km/h
