Downstream speed = (15 + x) km/h. The speed of a boat in still water is 15 km/hr. It goes 30 km upstream and returns downstream to the original point in 4 hours 30 minutes. Find the speed of the stream.
Solution: Let the speed of the train be x km/h. Downstream speed = (15 + x) km/h. Upstream speed = (15 - x) km/h. Time taken to go 30 km upstream = 30/(15 - x) hrs. Time taken to go 30 km downstream = 30/(15 + x) hrs. According to the Question, ? 30/(15 - x) + 30/(15 + x) = 9/2. ? 30(15 + x) + 30(15 - x)/(15 + x) (15 - x) = 9/2.
