Jin is standing still and watching an archer on a horse traveling away from a target. The archer is moving at a speed of 4 meters per second and shoots the arrow toward the target with a speed of 17 meters per second Which statement is supported by this scenario?

The arrow’s speed of 17 m/s is measured relative to the archer. Since the archer is moving away from the target at 4 m/s while shooting toward it, the arrow’s speed relative to Jin is 17 − 4 = 13 m/s. Thus, the arrow is moving at 13 m/s for Jin and 17 m/s for the archer, as stated in choice D.
