Answer:
1km per minute
Step-by-step explanation:
Given the table in the picture :
The average rate of change over the interval from 8 to 15 minutes will be :
Change in distance / change in time
Change in distance between 8 and 15 minutes :
Distance d1 at 8 minutes t1 = 7km
Distance d2 at 15 minutes t2 = 14km
Average rate of change = (d2 - d1) / (t2 - t1)
Average rate of change = (14 - 7)km / (15 - 8)min
Average rate of change = 7km / 7minutes
Average rate of change = 1km per minute
It would be 7 divided by 11( note: always divide the top by the bottom)
