SUMMARY
The discussion focuses on calculating the speed of a river based on a boat's travel times. The boat travels 15 km downstream in 3.1 hours, resulting in a downstream speed of 4.84 km/hr, while it takes 5.1 hours to travel the same distance upstream, yielding an upstream speed of 2.94 km/hr. The river's speed can be determined by analyzing the difference between the boat's speeds downstream and upstream, confirming that the river's speed is 1 km/hr when the boat's speed is 2 km/hr.
