Answer:
Correct option: B -> (5 1/2) * 2
Step-by-step explanation:
We can observe the number of different distances she hiked:
5 1/4, 5 1/2, 6 1/4, 7 1/4, 7 1/2 and 7 3/4.
In Susannah's equation, we have only 5 parts, so it's missing one distance, that is 5 1/2.
In this distance there are 2 circles, so she hiked this distance two times. Then, the missing value that Susannah should sum is:
(5 1/2) * 2
Correct option: B
