To find the total distance Andrea ran over the three days, we will add the distances she ran each day.
The distances are:
- Monday: 3.6 km
- Tuesday: 4.705 km
- Wednesday: 5.92 km
Now, we can perform the addition:
\[ 3.6 + 4.705 + 5.92 = 14.225 \text{ km} \]
So, Andrea ran a total of 14.225 kilometers over the three days.
