SUMMARY
The problem involves a boat traveling across a stream with a width of 1.5 km, where the boat's speed in still water is 6 km/h and the stream's current is 4 km/h. To calculate the effective speed of the boat across the stream, the Pythagorean theorem is applied, resulting in a speed of 7.21 km/h. The total time taken for the round trip across the stream is approximately 0.83 hours or 50 minutes.
