1
An airplane with an air speed of miles/hour heads directly North. A wind of 30 miles/hour is blowing from the West. What is the magnitude of the resultant ground speed of the plane?
2
A boat heads directly downstream. Assuming the boat can travel at miles/hour in still water and also assuming that the river is moving at 3 miles/hour, how fast will the boat be moving with respect to the shore?
3
An airplane which can fly miles/hour in still air is heading directly East. The wind is blowing from the East at 12.3 mi/hour. How fast will the plane be moving over the ground?
