Option C:
(11 + 8) + 1 = 11 + (8 + 1)
Solution:
Let us first define the associative property of addition.
<u>Associative property of addition:</u>
(a + b) + c = a + (b + c)
Option A: 5 + 3 = 3 + 5
This represents a commutative property of addition.
i.e. a + b = b + a.
So, it is not true.
Option B: 6 + 1 = 6 + 1
This is not under the property of associative.
It is not true.
Option C: (11 + 8) + 1 = 11 + (8 + 1)
(a + b) + c = a + (b + c)
This reflects the associative property of addition.
It is true.
Option B is the correct answer.
Hence (11 + 8) + 1 = 11 + (8 + 1) illustrates the associative property of addition.

Answer:
1.45
Step-by-step explanation: The question is asking "what was his average speed per miles per hour" and it says "26.1 miles in 3hrs and 18mins". So it wants to know the speed per hour.
Your gonna take 26.1 and divide it by the 18mins, which will give you 1.45
The tenth place is over 5 so it s rounded to 60.
