Question

X, Y and Z start at the same time in the same direction to run around a circular stadium. X completes a round in 160 seconds, Y in 260 seconds and Z in 200 seconds, all starting at the same point. After what time will they meet again at the starting point?

Answer 1

Answer:

They will meet again after 10400 seconds

Step-by-step explanation:

When they will meet again is determined by the lcm of the time they take to complete one revolution

Because the time when they meet must be divisible by the time taken by each of them..

So lcm of 160, 200, 260 is 10400

So the answer is 10400 secons..
