(c) Two straight roads meet at right angles at an intersection. A car is traveling due south towards the intersection at a constant speed of 60 miles per hour. A second car is traveling due west towards the same intersection at a constant speed of 70 miles per hour. How fast is the distance between the cars changing at the instant when the southbound car is 30 miles from the intersection and the westbound car is 40 miles from the intersection?
