Question

A streamer goes downstream and covers the distance between two ports in 3 hours. It covers the same distance in 5 hours when it goes upstream. If the stream flows at 3kmph, find what's speed of streamer upstream!

Answer 1

5kmph it takes .......

Answer 2

Answer:

Step-by-step explanation:

The speed of the stream=5km/he

Let the speed of streamer be=x km/hr

Speed of upstream=(x-5)km/hr

Time taken:

Upstream=5 hrs

Downstream=4 hrs

Given:

5(x-5)=4(x+5)

5x-25=20+25

1x=45

x=45
