Ram and Shyam are walking on two perpendicular tracks with speed \( 3 \mathrm{~m} \mathrm{~s}^{-1} \) and \( 4 \mathrm{~m} \mathrm{~s}^{-1} \), respectively. At a certain moment
\( \mathrm{P} \) (say \( \mathrm{t}=0 \mathrm{~s} \) ), Ram and Shyam are at \( 20 \mathrm{~m} \) and \( 40 \mathrm{~m} \) away from
W. the intersection of tracks, respectively, and moving towards the intersection of the tracks.
Shortest distance between them subsequently is
(1) \( 18 \mathrm{~m} \)
(2) \( 15 \mathrm{~m} \)
(3) \( 25 \mathrm{~m} \)
(4) \( 8 \mathrm{~m} \)
