Average number of people ride ferry boat = 62 or 63 people
Step-by-step explanation:
Given:
Number of people ride ferry boat
58 59 60 61 62 63 64 65 66 67
Find:
Average number of people ride ferry boat

Average number of people ride ferry boat = [625] / 10
Average number of people ride ferry boat = 62.5
Average number of people ride ferry boat = 62 or 63 people
