Time taken by Julian to complete 24 km trip to Guelph at 12 km/h =
hours
Time taken by Julian for return trip at 8 km/h = hours
As given, the total distance is 24 + 24 = 48 km.

Answer:
The average rate of change of change over the interval is 3.
Step-by-step explanation:
Given/Known:
( f(b) - f(a) ) / (b - a)
b = 8
a = -1
Solve:
( ((8)^2-4(8)-2) - ((-1)^2-4(-1)-2) ) / (8 - (-1))
(30 - 3)/(9)
27/9
3
The average rate of change is 3.
