The rate of change of car’s distance over time is equal to the velocity of the car. To find the rate of change of the given conditions, we use the formula veloctity = (Distance 2 + distance 1) / (time2 + time 1). In this case, we substitute, (60 + 300) miles / (1+5) hours equal to 60 miles per hour. Answer is D. 60 mph
