To find out how many miles Jina needs to bike on the last day, we first calculate the total distance she would need to bike over the 4 days to achieve an average of 50 miles per day. Since there are 4 days, she will need to bike a total of \(50 \times 4 = 200\) miles. She has already biked \(44 + 47 + 56 = 147\) miles. Therefore, the distance needed on the last day is \(200 - 147 = 53\) miles. Now, if Jina forgets to track her distances accurately, she could miscalculate her average. It's essential to write down each day's miles right after biking or keep a digital log. Also, remembering that averages are affected by all values is key – if she bikes less on the last day, it will pull the average down, making future challenges feel more daunting!
