A car traveling on a highway is 60 miles away from home after 1 hour, and is 300 miles away from home after 5 hours. What is the rate of change of the car’s distance over time?
If the car is traveling 60mph and is 300 miles away after 5 hours, the rate of change here is to divide 5 by 300. The answer is 60 (D). The problem here would look like 300/5=60. So the rate of change of the car's distance over time would be 60.
