Which distance, 18 miles \( (\mathrm{mi}) \) or 36 kilometers \( (\mathrm{km}) \), is greater?

To determine which distance is greater, we need to convert one of the units for comparison. Since 1 mile is approximately equal to 1.60934 kilometers, we can convert 18 miles to kilometers. Doing the math: 18 mi × 1.60934 km/mi ≈ 28.968 km. So, 18 miles is approximately 29 kilometers, making 36 kilometers the greater distance! If you're ever faced with a distance conversion again, remember that finding a reliable conversion factor is key! Common mistakes include rounding too early in the process, which can lead to inaccurate results. Always keep your calculations precise until the end!
