Question

10. A streamer goes downstream from one point to another in 9 hours.
It covers the same distance upstream in 10 hours. If the speed of
the stream be 2 km/h, find the speed of the steamer in still water
and distance.​

Answer 1

Step-by-step explanation:

time taken by streamer in upstream:10h

" " " " " downstream:9h

speed of stream :2km/hr

Let the speed of steamer be x

A•T•Q::-

10(x-2)=9(x+2)

10x - 20=9x+18

-20-18=9x-10

-38=-1x

38=x
