To estimate the total distance Andrea ran during March, April, and May this year, we first sum the kilometers she ran in each month.
March: 48.7 km
April: 31.2 km
May: 35.66 km
Total distance this year = 48.7 + 31.2 + 35.66
Let's calculate it step by step:
-
Adding March and April: \[ 48.7 + 31.2 = 79.9 \text{ km} \]
-
Now, adding May to the previous total: \[ 79.9 + 35.66 = 115.56 \text{ km} \]
Now we round the total distance to the nearest kilometer: \[ 115.56 \text{ km} \approx 116 \text{ km} \]
Next, we compare this distance to last year's distance: Last year, Andrea ran about 120 kilometers.
To find out how many more kilometers she ran last year compared to this year, we subtract this year's total from last year's total: \[ 120 \text{ km} - 116 \text{ km} = 4 \text{ km} \]
Thus, we can fill in the statements:
- Andrea ran about 116 km this year.
- This is about 4 km less than last year.
