Two people start at the same place and walk around a circular lake in opposite directions. One has an angular speed of 1 10-3 rad/s, while the other has an angular speed of 3.30 10-3 rad/s. How long will it be before they meet?

assume u1 is angular path1, u2 is angular path2
u1=w1*t, u2=w2*t, while u1+u2=2*pi rad
thus 2*pi=(w1+w2)*t, hence t=2*pi/(w1+w2).

The lake is 2*pi*radians around. If I stay in one place and you run at 4.30*10-3 rad/s, how many seconds would it take to go 2*pi*radians?
