Mack's average rate of change can be found to be 15 km per hour.
How to find the average rate of change?
To find Mack's average rate of change, you can use the formula:
Average Rate of Change = (Change in Distance) / (Change in Time)
In this case, you have the following data points:
At t = 0 hours, Mack is at 0 km.
At t = 4 hours, Mack is at 60 km.
So, the change in distance is 60 km - 0 km
= 60 km
The change in time is 4 hours - 0 hours
= 4 hours
Calculate the average rate of change:
Average Rate of Change = (60 km) / (4 hours)
= 15 km/hour
The missing table is:
Time / hours ( x ) Distance / km ( y )
