Directions: Answer the following questions below. Please show all work and circle your final answer.
1. A boat is heading due east in a river with a velocity of 10 km/hr with respect to the water. The
current of the water is flowing west with a velocity of 1.5 m/s. What is the velocity of the boat
with respect to an observer on the bank of the river?
2. An airplane is landing on an aircraft carrier with a ground velocity of 120 km/hr due east. A
person on the ship is viewing the plane land on the deck from behind the carrier with a velocity
of 112 km/hr due east. What is the velocity of the carrier?
3. A boat heading north crosses a wide river with a velocity of 13.5 km/hr relative to the water.
The river has a uniform velocity of 2.5 km/hr due east. Determine the boat’s velocity with
respect to an observer on shore.

4. A plane heading due east with a velocity of 250 km/hr encounters a strong wind heading North
West with a velocity of 35 km/hr. What is the ground velocity of the plane?
5. A boat heading due north crosses a river with a velocity if 3.0 m/s relative to the water. The
river has a uniform velocity of 0.5 m/s due west. Determine the boat’s velocity with respect to
an observer on shore. How far down stream is the boat once it makes it to the other side if the
river is 45m wide?
