D. Don is not moving.
Since both are traveling in the same direction at the same speed (25 mph), Don's velocity relative to Chip is 25 − 25 = 0 mph, so Don appears stationary from Chip's point of view.
Since both are traveling in the same direction at the same speed (25 mph), Don's velocity relative to Chip is 25 − 25 = 0 mph, so Don appears stationary from Chip's point of view.
