The speed of a swimmer in still water is $\displaystyle 20 \mathrm{~m} / \mathrm{s}$. The speed of river water is $\displaystyle 10 \mathrm{~m} / \mathrm{s}$ and is flowing due east. If he is standing on the south bank and wishes to cross the river along the shortest path, the angle at which he should make his strokes w.r.t. north is given by :
