Final answer:
The total distance walked by the group is 324 miles, which is found by multiplying 108 people by 3 miles per person.
Step-by-step explanation:
To determine the total distance walked by the group on Saturday around Lake E, you simply multiply the number of people by the distance each person walked. In this case, 108 people each walked 3 miles. By multiplying these two numbers together, you get the total distance walked:
108 people × 3 miles/person = 324 miles
So, the total distance walked by the group is 324 miles, which corresponds to option B).
