Let the speed of the stream be x km/hr The boat goes 30 km upstream and 44 km downsream. Hence, Thus, speed of stream is 3 km. the speed of a boat in still water is 8 km/hr. it can go 30 kmupstream and 44 km downstream in 10 hour. find the speed of thestream. Answer: - Let the speed of the stream be y km/hr. Speed of boat = 8 km/hr According to the given information, we have: 30/8-y + 44/8+y = 10 Now, solve this equation to get the answer.
