Options
- 4 kmph
- 3 kmph
- 2 kmph
- None of these

CORRECT ANSWER : 3 kmph

Discussion Board
answer is 3kmph

speed of boat in still water = (a+b)/2= 20 but he is given it as 10 half of actual speed of boat in still water.

there fore speed of stream = (a-b)/2 =6kmph but answer is 3kmph half of actual speed of stream.
