The problem states:

Melissa's family is going hiking around Teddy Roosevelt Island on the Swamp Trail. Each lap they walk is \(1 \frac{1}{4}\) miles. If they walk 4 laps, how many miles did they walk?

### Solution:
1. **Convert the mixed number to an improper fraction**:
   \[
   1 \frac{1}{4} = \frac{5}{4} \text{ miles}
   \]

2. **Multiply the distance of one lap by the number of laps**:
   \[
   \text{Total distance} = 4 \times \frac{5}{4}
   \]

3. **Simplify the expression**:
   \[
   4 \times \frac{5}{4} = \frac{20}{4} = 5 \text{ miles}
   \]

So, Melissa's family walked a total of **5 miles**.

### Relative Questions:
1. How do you convert a mixed number into an improper fraction?
2. What other methods could you use to multiply fractions?
3. If Melissa’s family walked half of a lap more, how many miles would they have walked?
4. How would the total distance change if each lap was \(2 \frac{1}{2}\) miles instead?
5. Can you express the distance of 4 laps as a decimal?

### Tip:
When multiplying fractions, always simplify the fractions first if possible to make the multiplication easier.

Melissa's family is going hiking around Teddy Roosevelt Island on the Swamp Trail. Each lap they walk is 1 1/4 miles. If they walk 4 laps, how many miles did they walk?

Learn how to calculate the total distance walked by multiplying mixed numbers. In this example, Melissa's family hikes 4 laps around Teddy Roosevelt Island, with each lap being 1 1/4 miles. Suitable for Grades 4-6.
