Jun 12, �� A speedboat, whose speed in 15 km/hr in still water goes 30 km downstream and comes back in a total of 4 hours 30 minutes. What is the speed of the stream in km/hr? km/hr; km/hr; 4 km/hr; 5 km/hr; km/hr; Answer: (4) 5 km/hr. Solution: Let the speed of the stream be x km/hr. Upstream Speed = 15 + x. Downstream Speed = 15 � x. Apr 03, �� If the downstream speed is kmph and upstream speed is kmph then, Example: A man can row upstream at 7 kmph and downstream at 10 kmph. Find . Some Important Shortcuts: Suppose a man can row a boat at a speed of r km/hr in still water and covers the same distance up and down in a stream while a stream flows at a speed of s km/hr. His average speed will be: A man rows downstream by covering a certain distance in p1 hours and returns the same distance upstream in p2 hours.
