Answer 1

To determine after how many additional hours Amelia will have walked more than 30 miles, we need to first find out how many more miles she needs to walk.

1. **Calculate the remaining distance**:
- Amelia has already walked 11 miles.
- She wants to walk more than 30 miles.
- Total distance needed = 30 miles - 11 miles = 19 miles.

2. **Calculate the time needed to walk that distance**:
- She walks at a speed of 4 miles per hour.
- Time = Distance / Speed = 19 miles / 4 miles per hour = 4.75 hours.

3. **Determine when she will have walked more than 30 miles**:
- Since 4.75 hours is equivalent to 4 hours and 45 minutes, we consider the time needed in hours.
- This is just less than 5 hours.

Now we need to find the number of additional hours she will need to walk to exceed 30 miles. Since we are considering whole hours and she needs slightly less than 5 hours, the smallest whole hour that exceeds 4.75 is 5 hours.

Therefore, after **5 additional hours**, she will have walked just over 30 miles.
