FINDING MEETING POINT

Teacher's questions

FINDING MEETING POINT

"A","B","C" STARTS AT THE SME TIME IN THE SAME DIRECTION TO RUN AROUND A RECTANGULAR GARDEN. "A" COMPLETES ONE FULL ROUND IN 252 SECONDS, "B" IN 308 SECONDS AND "C" IN 198 SECONDS. AFTER, WHAT TIME WILL THEY MEET AGAIN AT THE SAME STARTING POINT?

This question is really challenging for me to arrive the answer but not you.

Thanks for your time to solve my problems...

Re: FINDING MEETING POINT

I think like this:
"А" 252=2.2.3.3.7 (sec.) ; "B" 308=2.2.7.11 (sec.) ; "C " 198=2.3.3.11 (sec.)
We are looking for a number that is divided by 252 and 308 and 198.
It is 2.2.3.3.7.11=2 772 (seconds)
After 2 772 (sec.) the subject of "A" will have traveled 11 times and will be at the starting point.
After 2 772 (sec.) the subject of "B" will have traveled 9 times and will be at the starting point.
After 2 772 (sec.) the subject of "C" will have traveled 14 times and will be at the starting point.

The three objects will meet simultaneously at the starting point itself,from they left.
