To find the magnitude of the boat's resultant velocity with respect to the starting point, we can use the Pythagorean Theorem, as the boat's speed in still water and the river's current are perpendicular to each other.

Given:

Speed of the boat in still water (east) = 4 m/s

Speed of the river current (south) = 3 m/s

Using the Pythagorean Theorem:
