Speed of a boat in still water is 15 km/h. It goes 30 km upstream and returns back at the same point in 4 hours 30 minutes. Find the speed of the stream. from Class 10 CBSE Previous Year Board Papers | Mathematics Speed Of The Boat In Still Water Is 11 Kilometres Per Hour Solved Board Papers. Speed of water = 15km/hr. Distance travelled upstream and downstream = 30 km. Let, speed of stream be x km/hr. So, time taken to travel 30km upstream = 30/x. and, time taken to travel 30km downstream = 30/15+x. Time taken to travel 30km upstream and 30km downstream = 4 hour 30 min or 9/2 hours. So, the equation formed will be. 30/x + 30 /5(). A motorboat whose speed is 15 km/hr in still water goes 30km downstream and comes back in four and a half hours. The speed of the stream is?
