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?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 2 min 5 sec.
Time = Distance/Speed
The relative speed between the man and the woman = 37 + 35 = 72 km/h = 72(1000)/60(60) = 20m/s
The man is moving at a speed of 72 km/h with respect to the woman.
To meet the woman, the man has to cover a distance of 2500m with a speed of 20 m/s.
Time taken = 2500/20 = 125 sec = 2 min 5 sec.
