Numerical Ability
Time Distance and Speed
A man takes twice as long to row a distance against the stream as to row the same distance in favour of the stream. The ratio of the speed of the boat (in still water) and the stream is:
A. 2 : 1
B. 3 : 1
C. 3 : 2
D. 4 : 3
Read Solution (Total 1)
-
- B. 3 : 1
upstream speed/ downward speed = 1/2
If B is speed of boat in still water and w is speed of water stream
(B-w)/(B+w) = 1/2
2B-2w = B+w
B= 3w
B/w= 3/1 .... option B - 13 years agoHelpfull: Yes(3) No(0)
