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  ?

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.
