Ram Shyam are walking on two perpendicular tracks with speed `3ms^(-1) and 4 ms^(-1)`, respectively. At a certain moment (say t = 0s), Ram and Shyam are at 20 m and 40 m away from the intersection of tracks, respectively, and moving towards the intersection of the tracks.
Shortest distance between them subsequently is

A

18m

B

15m

C

25m

D

8m

`tan 53^(@)=(y)/(20)`
`y=20xx(4)/(3)=(80)/(3)`
`sin 37^(@)=(d)/(40-(80)/(3)) d=(3)/(5)[(40)/(3)]=8m`
