To find the rate at which Oliver practiced the piano in minutes per day, we need to first determine the total number of days in 4 weeks and then divide the total minutes practiced by that number of days.
1. Calculate the number of days in 4 weeks:
\[
4 \text{ weeks} \times 7 \text{ days/week} = 28 \text{ days}
\]
2. Now, divide the total minutes practiced (448 minutes) by the total number of days (28 days):
\[
\frac{448 \text{ minutes}}{28 \text{ days}} = 16 \text{ minutes/day}
\]
Thus, Oliver practiced the piano at a rate of **16 minutes per day**.
