Question

A streamer goes downstream and covers the distance between two ports in 5 hours while it covers the same distance upstream in 6 hours. If the speed of the stream is
1 km/h, find the speed of the streamer in still water and the distance between two ports.

Answer 1

Answer:

steamer speed=11km/hr

Step-by-step explanation:

let speed of steamer X km/hr

d/s speed =X+1 km/hr

distance =speed. X. time

= (X+1)x5

=5x+5

u/s speed=(x-1) km/hr

distance=(x-1)x6

=6x-6

5x+5=6x-6

5x-6x=-6-5

-x=-11

X=11 km/hr
