Physics

To cross the river in the shortest time, the boat should head directly across the river without being affected by the current as much as possible. The boat's velocity in still water is 4 m/s. When heading directly across, this velocity is perpendicular to the river flow.

Given

The width of the river is 300 m.

The speed of the boat in still water is 4 m/s.
