Answer:

2

Step-by-step explanation:

The rate of change in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [ 30, 50 ]

f(b) = f(50) = 100 ← from graph

f(a) = f(30) = 60 ← from graph , thus

average rate of change = [tex]\frac{100-60}{50-30}[/tex] = [tex]\frac{40}{20}[/tex] = 2
