Problem: A river lies in the east - west direction. The current in the river has a velocity relative to the ground of 3 mi/hr toward the east. A boat has a maximum speed relative to the water of 4 mi/hr. The boat is heading so as to get across the river as soon as possible. The speed (magnitude of velocity) of the boat relative to the ground is A. 1 mi/hr B. 3 mi/hr C. 4 mi/hr D. 5 mi/hr E. 7 mi/hr
