Answer:

5 km/hr

Explanation:

The motion of the boy and the rain are perpendicular to east other (boy moving on the x-axis and rain on the y-axis). We need the hypotenuse of a right triangle with sides of 3 km/hr and 4 km/hr.

c² = a² + b² = (3 km/hr)² + (4 km/hr)² = 9 km²/hr² + 16 km²/hr² = 25 km²/hr².

c = (25 km²/hr²) = 5 km/hr.
