STEP 1

1. Carmen swims a total of $4000$ meters each week.
2. We need to convert meters to kilometers.
3. $1$ kilometer is equal to $1000$ meters.

STEP 2

1. Define the conversion factor.
2. Set up the conversion calculation.
3. Calculate the total kilometers.

STEP 3

Define the conversion factor between meters and kilometers.
$$1 \text{ kilometer} = 1000 \text{ meters}$$

STEP 4

Set up the conversion calculation using the conversion factor.
$$\text{Kilometers swum} = \frac{\text{Total meters swum}}{\text{Meters per kilometer}}$$

STEP 5

Substitute the known values into the conversion calculation.
$$\text{Kilometers swum} = \frac{4000 \text{ meters}}{1000 \text{ meters per kilometer}}$$

Perform the division to find the number of kilometers.
$$\text{Kilometers swum} = 4 \text{ kilometers}$$ Carmen swims a total of:
$$\boxed{4 \text{ kilometers}}$$
