Imagine that you lived in a dot on the surface of an expanding balloon, and as you looked to more distant dots, you observed the following: A dot at a distance of 5 centimeters from you is moving away from you at a speed of 1 centimeter per hour (1 cm/hr). A dot at a distance of 10 centimeters from you is moving away from you at a speed of 2 centimeters per hour (2 cm/hr). A dot at a distance of 15 centimeters from you is moving away from you at a speed of 3 centimeters per hour (3 cm/hr).Which equation below correctly states the relationship between the dot distances and speeds as observed by you?
