A boat covers a certain distance downstream in 2 hour, while it comes back in 2 1/2 hours. If the speed of the stream be 5 kmph, what is the speed of the boat in still water? A. 40 kmph B. 30 kmph C. 35 kmph D. 45 kmph Answer: D. 45 kmph Explanation: Let the speed of the boat in still water be x kmph. Then, Speed downstream = (x + 5) kmph. Thus the speed of the boat in still water is 20 km/h. 2) A steamer goes downstream and covers the distance between two ports in 4 hrs., while it covers the same distance upstream in 5 hrs. If the speed of the stream is 2km/h, find the speed of the steamer in still water.
