Answer:
Step-by-step explanation:
Let the speed of a boat in still water be x km/hr and the speed of the stream be y km/hr, then
Speed downstream = (x + y) km/hr
Speed upstream = (x- y) km/hr

Answer:
Let the speed of the stream be x km/hour.
Then speed of the boat in downstream will be (10+x)km/hour.
And speed of the boat in upstream will be (10−x)km/hour.
As given,the boat travels 26km downstream and 14km upstream at the same time.
10+x
26
=
10−x
14
=26(10−x)=14(10+x)
=260−26x=140+14x
=120=40x
x=3km/hour
Speed of the stream is 3 km/hour.
