Question

A steamer goes downstream from one point to another in 6 hours. It covers same distance upstream in 7 hours. If the speed of the stream is 2 km per hour, find the speed of the stream hour in still water

Please answer it fast

Answer 1

let speed of boat=x km/hr
and here speed of stream =2km/hr given.
now speed of up stream=(x-2)km/hr
spees of down stream=(x+2)km/hr


acc/q
,6(x+2)=7 (x-2)
6x+12=7x-14
-x=-26
x=26km/hr.
