Hi,

"in point A" in the following sentence is correct? Could I replace "in" by "at"?

Ahmed and Sara move from point A in the direction shown with the same speed.
Ahmed walks around the square garden and Sara walks around the rectangular garden.

How many rounds does Ahmed have to walk to meet Sara in point A again for the first time?


Thanks

"In" is not a good choice. Use "at".
