A single engine private plane flies due North for an hour and $18$ minutes at an average speed of $110 \mathrm{km}/\mathrm{h}$. It then turns and flies at the same average speed for an hour and a half on a bearing of $130°$. At the end of this time, determine how far the plane has travelled. [Enter the value excluding units]
