Salma is participating in a 5-day cross-country biking challenge. She biked for \( 79,61,45 \), and 67 miles on the first four days. How many miles does she need to bike on the last day so that her average (mean) is 62 miles per day?

To find out how many miles Salma needs to bike on the last day, we can start by calculating the total distance she needs to cover for her average to be 62 miles over 5 days. Since she wants an average of 62 miles for 5 days, the total distance required would be: \[ 62 \text{ miles/day} \times 5 \text{ days} = 310 \text{ miles} \] Next, we add the miles she biked on the first four days: \[ 79 + 61 + 45 + 67 = 252 \text{ miles} \] Now, we subtract the distance she has already biked from the total distance needed: \[ 310 - 252 = 58 \text{ miles} \] So, Salma needs to bike 58 miles on the last day to achieve her goal of an average of 62 miles per day! 🏍️💨 Keep in mind that tracking progress is always helpful. Maybe she could even use a fun app to log her miles and keep herself motivated—there's nothing like seeing the numbers add up! Plus, don’t forget to celebrate the little milestones along the way; it's what makes a challenge fun! 🎉
