Today’s Problem: Circle Time

Mr. Sutton’s class sits in a circle, each student spaced equally apart from each other.

If the 4th student sits directly opposite the 13th student, how many students are in Mr. Sutton’s class?

Extension:

If the entire 4th grade at the school sits in a larger circle, how many students are there if the 11th student sits directly opposite the 49th student?

If the entire school sits in a larger circle, how many students are there if the 34th student sits opposite the 76th student?
