To determine the boat's speed with respect to an observer on shore, we can use the Pythagorean Theorem since the boat's velocity (north) and the river's current (east) are perpendicular to each other.

Given:

Velocity of the boat relative to the water (north) = 10.00 km/h

Velocity of the river current (east) = 5.00 km/h

Using the Pythagorean Theorem:
