Question

A streamer goes downstream and covers the distance between two ports in 4 hours and covers the same distance upstream in 5hrs. Find the speed of the streamer, if the water is flowing at a speed of 1.5km/h. ( Please give strp by Step ans) ​

Answer 1

Answer:

13.5Km/h

Step-by-step explanation:

Given

Speed of the stream in still water =1.5km/h

Let speed of the streamer =xkm/h

Speed downstream =(x+1.5)km/h

Speed upstream =(x−1.5)km/h

According to the given condition,

(x+1.5)×4=(x−1.5)×5

4x+6=5x−7.5

x=13.5

Hence , Speed of streamer in still water is

13.5km/h.
