Question

You run 7 miles in one hour and 21 miles in three hours what’s the rate of change

Answer 1

If you run 7 miles in 1 hour, that is your rate of change. When the independent is at one, that is your rate of change. We can see the rate of change does not change. I also run 21 miles in three hours. If we divide y by x, we get the same number as compared to one mile. So, the rate of change is 7 miles as each hour passes.
