Answer 1

hello mate here is your answer

They meet after 30 minutes at the starting point for first time.

Step-by-step explanation:

Since we have given that

Number of runners = 4

Time they took to complete one round is given by

200 sec, 300 sec, 360 sec, 450 sec.

So, We need to find the time they meet at the starting point for first time.

L.C.M. of 200, 300, 360, 450 = 1800 sec

1800 sec = 30 minutes

Hence, they meet after 30 minutes at the starting point for first time.
