Q15. Two men P and Q start swimming towards each other from the deep end and shallow end respectively of a swimming pool in funicity. They start their swimming simultaneously in the length of 300 m pool. The ratio of the their speeds is 1 : 2 respectively. Each swimmer rests for 6 seconds once he reaches the other end and starts swimming back. Where will they meet for the second time in the still water of swimming pool ?
30 m from the shallow end
at the shallow end
at the deep end
can’t be determined
None of these
Solution:
Ratio of their speeds = 1 : 2
It means deep end’s man reaches at shallow end in double time as compared to shallow end’s man. When shallow ends man reaches at deep end, deep end’s man reaches at centre of the required distance.
Again, when deep end’s man reaches at shallow end, shallow end man also reaches at its original point in same time.
So, second time they will meet at shallow end.
