Two persons start running simultaneously around a circular track of length 300 m from the same point at speeds of 15 km/hr and 25 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 choice.
A) 27 sec	B) 87 sec	C) 67 sec	D) 47 sec	E) 37 sec
Explanation:   Time taken to meet for the first time anywhere on the track   = length of the track / relative speed   = 300 / (15 + 25)5/18 = 300x 18 / 40 x 5 = 27 seconds.   27 secnswer: 27 sec
