Final answer:
To find the average number of miles Gianna would need to travel per day to reach her goal of 48.5 miles, the formula (Total miles - Miles traveled) / Days remaining = Average miles per day can be used.
Step-by-step explanation:
To determine the average number of miles Gianna would have to travel per day to reach her goal, we can use the formula:
(Total miles - Miles traveled) / Days remaining = Average miles per day
In this case, Gianna wants to travel 48.5 miles in total, and she has already traveled 18 miles. She plans to ride for 5 more days. Plugging in these values into the formula, we get: (48.5 - 18) / 5 = X
Simplifying the equation, X = 30.5 / 5 = 6.1 miles per day. Therefore, Gianna would need to travel an average of 6.1 miles per day to reach her goal of 48.5 miles in a week.
