Final answer:
The equation for the distance after 1995 is d = 70t.
Step-by-step explanation:
The equation for the distance after 1995 is d = 70t. This is because the question states that Pennsylvania changed its maximum speed limit on rural roads, indicating that the new maximum speed limit is 70 mph. Therefore, the distance traveled (d) is equal to the speed (70 mph) multiplied by the time (t) in hours.
