SUMMARY
The discussion focuses on calculating the time required for a hunter to cross a 1.5 km wide river flowing at 6.6 km/h using a powerboat with a maximum speed of 14 km/h. To determine the crossing time, one must first calculate the net velocity of the boat by considering the river's current. The angle of approach is calculated using the formula θ = tan-1(vriver/vboat). Finally, the time is derived from the distance and net velocity, ensuring all units are appropriately converted.
