To find out if Andrea reached her goal, we first need to calculate the total distance she ran on Friday and Saturday combined.
The distances are as follows:
- Friday: 3.174 kilometers
- Saturday: 4.08 kilometers
Now, we combine these distances:
\[ \text{Total distance on Friday and Saturday} = 3.174 + 4.08 = 7.254 \text{ kilometers} \]
Next, we need to find out how much Andrea aimed to run on Sunday. According to the problem, she wanted to run at least 3 more kilometers on Sunday than the total from Friday and Saturday.
So, we calculate what her goal for Sunday was:
\[ \text{Goal for Sunday} = \text{Total distance on Friday and Saturday} + 3 = 7.254 + 3 = 10.254 \text{ kilometers} \]
Now, we check how much she actually ran on Sunday:
- Sunday: 11.9 kilometers
Now we compare the distance she ran on Sunday to her goal:
\[ 11.9 \text{ kilometers} > 10.254 \text{ kilometers} \]
Since 11.9 kilometers is greater than 10.254 kilometers, Andrea did reach her goal.
To summarize:
- Total distance on Friday and Saturday: 7.254 kilometers
- Goal for Sunday: 10.254 kilometers
- Distance ran on Sunday: 11.9 kilometers
- Did she reach her goal? Yes.
