SUMMARY
The discussion focuses on calculating the resultant velocity of a swimmer crossing a river. The swimmer moves at 3.5 m/s at an angle of 30° North of East, while the river flows southward at 4.0 m/s. The resultant velocity is determined to be 3.8 m/s at an angle of 37° South of East. The calculations involve breaking down the swimmer's velocity into components and applying trigonometric principles.
