A person goes in a boat downstream at x km/hr and upstream at y km/hr. What is the ratio of speed of the boat in still water to the speed of water?
Answer
The correct answer is C: (x+y)/(x–y). Speed of boat in still water = (x + y)/2. Speed of stream (water) = (x – y)/2.
- A.x/y
- B.y/x
- C.(x+y)/(x–y)✓ Correct
- D.(x–y)/(x+y)
Speed of boat in still water = (x + y)/2. Speed of stream (water) = (x – y)/2. Therefore ratio = (x+y)/2 : (x–y)/2 = (x+y)/(x–y).
