A boatman takes twice as long to row a distance against the stream as to row the same distance with the stream. Find the ratio of speeds of the boat in still water and the stream. ?
-
- 2 : 1
- 3 : 1
- 1 : 2
- 1 : 3
Correct Option: B
Let boatman's speed upstream x
And his speed downstream = 2x
∴ Ratio = (Speed in still water) : (Speed of stream)
= (2x + x/2) : (2x - x/2)
= 3x/2 : x/2
= 3 : 1
