Two people start at the same place and walk around a circular lake in opposite directions. One has an angular speed of 2.46 x 10-3 rad/s, while the other has an angular speed of 7.91 x 10-3 rad/s. How long will it be before they meet?

Answer 1

d1 + d2 = 2pi rads = A complete circle.
V1t + V2t = 2pi
2.46*10^-3 + 7.91*10^-3 = 6.28
10.37*10^-3t = 6.28
t = 606 s.
