A motorboat, whose speed is 24 km/h in still water, takes 1 hour more to go 32 km upstream than to return downstream to the same spot. Find the speed of

Total Distance = 32km Speed in Still Water = 24km/hr Let the speed of stream be 'x' kmph then, Speed moving upstream = 24-x Speed moving downstream = 24+x We know that is time On reducing it to a quadratic equation, we get - On solving it by splitting the middle term method (8&72 as factors) we get, x = 8 or -72 Since, the speed cannot be negative, x = 8 Therefore, the speed of the stream is 8 km/hr
