2. \( 4.5 \mathrm{~km}=\square \mathrm{m} \)

To convert kilometers to meters, simply remember that 1 kilometer equals 1,000 meters. So for 4.5 kilometers, you multiply by 1,000. Thus, \( 4.5 \, \text{km} = 4.5 \times 1,000 \, \text{m} = 4,500 \, \text{m} \). It's as easy as pie—just multiply! This is a common conversion you might need in real life, whether you're measuring the distance for a run, navigating on a road trip, or planning out a hiking trail. Knowing how to switch between kilometers and meters will make your planning smoother and more accurate!
