Two persons start running simultaneously around a circular track of length 200 m from the same point at speeds of 6 km/hr and 12 km/hr. When will they meet for the first time any where on the track if they are moving in opposite directions?	Choose the correct answer:  A) 28 sec  B) 37 sec  C) 17 sec  D) 60 sec  E) 27 sec
Time taken to meet for the first time anywhere on the track   = length of the track / relative speed   = 200 / (6+ 12)5/18 = 300* 18 / 18 * 5 = 60 seconds.   Answer : 60 sec
