Two persons start running simultaneously around a rectangular track of length 700 m from the same point at speeds of 45 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?
50 sec.
42 sec.
25 sec.
36 sec.
Time taken to meet for the first time = length of the track / relative speed = 700 / (45 + 25) = (700*18)/(70*5) = 36 sec.
