Question : Two people A and B started running from the same point on a circular track of length 400 m in opposite directions with initial speeds of 10 m/s and 40 m/s, respectively. Whenever they meet, A's speed doubles and B's speed halves. After what time from the start will they meet for the third time?
Option 1: 30 sec
Option 2: 24 sec
Option 3: 26 sec
Option 4: 28 sec
Correct Answer: 26 sec
Solution : Given: Total length of the track = 400 m Speed of A = 10 m/sec Speed of B = 40 m/sec They are running in the opposite direction ⇒ Relative speed = 10 + 40 = 50 m/sec We know, Speed = $\frac{\text{Distance}}{\text{Time}}$ Time
