1. **State the problem:** Betsy swam 690 meters each day for 2 weeks. We need to find how many kilometers she swam in total. 2. **Identify the formula and conversion:** Total distance swam = daily distance × number of days. Since 1 meter = 0.001 kilometers, we will convert meters to kilometers after finding the total meters. 3. **Calculate the total meters:** Number of days in 2 weeks = $2 \times 7 = 14$ days. Total meters swam = $690 \times 14 = 9660$ meters. 4. **Convert meters to kilometers:** Total kilometers = $9660 \times 0.001 = 9.66$ kilometers. 5. **Final answer:** Betsy swam **9.66 kilometers** in 2 weeks.
