Answer: 14.225 kilometers.
Explanation:
Given : Andrea enjoys running. She keeps a daily journal to record how far she runs. She wears a pedometer to calculate the exact distance in kilometers.
Monday 3.6
Tuesday 4.705
Wednesday 5.92
By using the addition operation, the total distance, in kilometers, that Andrea ran over the three days will be :
3.6 +4.705 +5.92=14.225
Hence, the total distance that Andrea ran over the three days = 14.225 kilometers.
