The situation of a plane moving in the medium of moving air is similar to a motorboat moving in the medium of moving water. In a river, a boat moves relative to the water and the water moves
relative to the shore. The result is that the resultant velocity of the boat is different than the boat's
speedometer reading, thanks to the movement of the water that the boat is in. In the diagram below,
a top view of a river is shown. A boat starts on the west side (left side) of the river and heads a
variety of directions to get to the other side. The river flows south (down). Match the boat headings
and boat speeds to the indicated destinations. Use each letter once.
