A boat was traveling at 15 mph when a passenger threw an object at 10 mph in the same direction the boat was moving. A friend, standing on the shore, observed the object moving with a speed of 25 mph. The passenger observed the object moving with a speed of 10 mph. Why were the two observations different? A. The passenger and the friend were watching the object from two different frames of reference. B. The distance between the boat and the shore gave the friend a different viewing angle. C. The current of the river affects the speed of the boat relative to shore. D. Objects appear to move more slowly when they move away from the observer.
