Step-by-step explanation:

Two athletes a and b start running around the field at same time another from the same point if the althelte a takes 10 minutes and b takes 15 minutes to complete one round then find after what time will they meet again understand. and how many rounds will be completing in the found time

Both athletes start from same point

one complete cycle in 10 minutes

another complete cycle in 15 minutes

To find when they will meet again

We need to find LCM of 10 & 15

10 = 2 * 5

15 = 3 * 5

LCM = 2 * 3 * 5 = 30

After 30 Mins they will meet again

One will complete 30/10 = 3 rounds

Another will complete = 30/15 = 2 rounds
