Answer 1

Answer:

200 second

So, you have to find lcm of this three number with different method.

A and B are moving in same direction, lcm of 25 and 40 is 200, so after every 200th second they will meet each other.

And c is moving in reverse direction but he will complete his round after 50 seconds, so at 200 second all will meet at same point.

Please mark it as brainlist.
