Let AB be a diameter of a circular track. Tom starts from point A running clockwise on the track. At the same time Jerry starts from Point B running counterclockwise on the track. Each person runs at a constant speed. They first meet after Tom has run 200 feet. They next meet after Jerry has run 300 feet past their first meeting point. What is the length of the track in feet?

1000 ft
because...
200*2=400
and
300*2=600
then
400+600=1000ft
