Physics - Kinematics Question with Solution | TestHub

Two aeroplanes, P and Q, move with constant velocities $3m{s}^{-1}$ and $6m{s}^{-1}$ along two mutually perpendicular straight tracks toward the intersection point O. At the moment $t=0$, aeroplanes P and Q were located at distances $105mm$ and $2\times 10^{4}cm$ respectively from the point O.
