Car A is driving south, away from an intersection. Car B is approaching the intersection and is moving west. At what rate is the distance between the cars changing at the instant when car A is 40 miles from the intersection and traveling at 55 mph and car B is 30 miles from the intersection and traveling at 45 mph? Are the cars getting closer together or farther apart at this time?

You are a construction worker standing still on 12th Ave N in Fargo, and you watch a minivan drive past at 25 mi/hr eastward. A kid in the back throws a ball at his brother in the front seat at 19 mi/hr. How fast does the ball move, as observed by you? (Positive indicates east, negative indicates west.) ? How fast does the ball move, according to the kid who threw it? If instead the kid in the front seat throws a rock at the kid in the back seat at 19 mi/hr, how fast would you observe the rock to travel?

A student is walking with a constant speed of ??1meters per second along High Street and sees a puddle ??1 meters ahead of her. A bus driver is driving parallel to the student along High Street as well.
