In a circular race of 400 m in length, A and B start at speeds of 10 m/s and 16 m/s, respectively, at the same time from the same point. After how much time will they meet for the first time at the starting point when running in the same direction?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 200 s
According to the question
They meet for the first time at the starting point = LCM of (distance/relative speed)
= LCM of (400/10) and (400/16)
= LCM of 40 and 25
= 200 sec
