Question

the answer is 20 but how is 20

Solve correctly 

Two trains run around circular paths of equal radius
R = 10 km in opposite directions. The faster one has
its horizontal coordinate described by x = Rсos(2лt)
with t in hours. The slower one has its horizontal
coordinate described by x = Rcos(2лt/3). How many
times do the trains pass each other during 20 round
trips of the faster train if they leave the same station
at the same time t = 0?
a. ( 20.0)
O b. (6.67)
c. (None of the other 4 answers)
O d. (0.942)
O e. (60.0)
