In a circular race of 2500 m, a man and a woman start from a point towards opposite directions with speeds of 37 km/h and 35 km/h, respectively. After how much time from the start of the race will they meet for the first time?
Answer & explanation
Correct answer: option 3
Relative speed ( when moves in opposite direction ) = 37 + 35 = 73 km/h
72 km/h = 72 × \(\frac{5}{18}\) m/sec = 20 m/sec
Total distance to be cover = 2500 m
Time taken = \(\frac{Distance }{Speed}\)
= \(\frac{2500 }{20}\)
= 125 seconds
= 2 minutes 5 second
