Two girls started running simultaneously around a circular track of length 1200 m from the same point at speeds of 30 km/hr and 50 km/hr. When will they meet for the first time any where on the track if they are moving in opposite directions?  Choose the most appropriate option.
A) 50	B) 51	C) 52	D) 53	E) 54
Time taken to meet for the first time anywhere on the track   = length of the track / relative speed   = 1200 / (30 + 50)5/18 = 1200* 18 / 80 * 5 = 54 seconds.   Answer:54
