A flag on a bus is fluttering in the North direction. The wind is blowing in the East direction. Which of the following statements is true?

Two persons $P$ and $Q$, start from points $A$ and $B$, respectively, as shown in the figure. $P$ and $Q$ have speed $v=12 \mathrm{m} {\mathrm{s}}^{-1}$, towards point $O$. When the distance between $P$ and $Q$ is $120 \mathrm{m}$, then $Q$ increases its speed to $15 \mathrm{m} {\mathrm{s}}^{-1}$. Then, find out who will reach point $O$ first.

Two aeroplanes fly from their respective positions $A$ and $B$, starting at the same time and reach point $C$ simultaneously when the wind was not blowing. On a windy day, they head towards $C$, but both reach point $D$ simultaneously at the same time which they took to reach $C$. Then, the wind is blowing in
