Mr Wong is riding his bicycle north away from an intersection at a rate of 15 miles per hour. Ms K is driving her car towards the intersection from the West at a rate of 30 miles per hour. If Mr Wong is 0.4 miles from the intersection, and Ms K is 1 mile from the intersection, at what rate is the distance between the two of them changing (rounded, not truncated, to 3 decimal places with the correct sign and no units)?
