Final answer:
Amy's daily step total for the second day of her fitness competition was 9,200 steps. This was calculated by subtracting her first-day steps from the total and then dividing the remaining steps by the number of days left.
Step-by-step explanation:
The student, Amy, wants to calculate the number of steps she took on the second day of her fitness competition. Given that Amy's lowest step count was on the first day with 8,500 steps, and she had a total of 45,300 steps over 5 days, we can find out her daily steps for the remaining 4 days. To do this, we first need to subtract the steps she took on the first day from the total steps.
Total steps over 5 days = 45,300
Subtract the steps from the first day: 45,300 - 8,500 = 36,800
This is the total number of steps Amy took over the next 4 days. Since she took the same number of steps each day, we divide the sum by 4 to find the daily step count for days 2 through 5.
36,800 / 4 = 9,200 steps per day for the second, third, fourth, and fifth days.
