A cyclist recorded the number of miles per day she cycled for five days. The recordings were as follows: 13, 10, 12, 10, 11. The mean number of miles she cycled per day was __________.

To find the mean (average) number of miles cycled per day, we need to add all the values together and divide by the number of days.

The recordings are: 13, 10, 12, 10, 11.

### Step 1: Add the values.
\[
13 + 10 + 12 + 10 + 11 = 56
\]

### Step 2: Divide the sum by the number of days (5 days).
\[
\frac{56}{5} = 11.2
\]

So, the mean number of miles she cycled per day is **11.2 miles**.
