Academics

Two runners start simultaneously from the same point on a circular 200-m track and run in the same direction. One runs at a constant speed of 6.20 and the other runs at a constant speed of 5.50 . Can some one please explain part b and d.

a) When will the fast one first overtake ("lap") the slower one?---286 s

b) How far from the starting point will each have run at that instant?

c) When will the fast one overtake the slower one for the second time?---571 s

d) How far from the starting point will they be at that instant?
