Airplanes A and B are flying with constant velocity in the same vertical plane at an angles 30° and 60° w.r.t. the horizontal, respectively as shown in the figure given below. The speed of A is 100√3 ms-1. At time t = 0s, an observer in A finds B at a distance of 500 m. This observer sees B moving with a constant velocity perpendicular to the line of motion of A. If at t = t₀ , A just escapes being hit by B, t₀ (in second) is
