Question 71

A boat running downstreams covers a distance of 16 km in 2 hours while for covering the same distance upstream it takes 4 hours. What is the speed of the boat in still water?

Solution

Let the speed of the boat in still water be B and the speed of the water be W.
So, speed of the boat downstream is B+W and the speed of the boat upstream is B-W.

From the information given, the speed of the boat downstream is 16/2 = 8 kmph
Speed of the boat upstream is 16/4 = 4 kmph

Hence, B+W = 8 and B-W =4
So, B = 6 kmph and W = 2 kmph
