@Suraj.
5/18 is for converting the km/hour into m/sec.

60 * 5/18 = 16.6666667. Then, Why it is divided by 50/3?

You all converted km --> m. Why don't you convert seconds into hours?
Then S=d/t,
Then D=s*t.
But t=9 sec.
If we convert it into hours form we will get 1/400.
Then d=60*1/400.
Is it correct method. Let me explain in this way guys.
