A boat while travelling upstream covers a distance of 29 km at the speed of 6 km/h, whereas while travelling downstream it covers the same distance at a speed of 12 km/h. What is the speed of the boat in still water?

Q: A boat while travelling upstream covers a distance of 29 km at the speed of 6 km/h, whereas while travelling downstream it covers the same distance at a speed of 12 km/h. What is the speed of the boat in still water?

Speed of boat in still water = 1/2 (12 + 6) = 9 kmph.

6 kmph
8 kmph
9 kmph
11 kmph

Correct Answer: 9 kmph

Explanation:

Speed of boat in still water = 1/2 (12 + 6) = 9 kmph.
