The speed of boat in still water is 15 kilometre per hour it can go 13 km upstream and return downstream in 4 hours 30 minutes find the speed of the stream?
Verified Answer
The speed of boat in still water is 15 kilometre per hour it can go 13...
Let the speed of the stream be x km/h.
It is given that the speed of a boat in still water is 15 km/h.
Now,
Speed of the boat upstream = Speed of the boat in still water − Speed of the stream = (15 − x) km/h
Speed of the boat downstream = Speed of the boat in still water + Speed of the stream = (15 + x) km/h
We know that
Time=Distance/Speed
Time is taken for upstream journey + Time taken for the downstream journey = 4 h 30 min

Since speed can not be negative, therefore, x = 5.
Thus, the speed of the stream is 5 km/h.
