11a) How many miles are equal to 1600 km , rounded to the nearest 0.1 mi.? b) How many kilometres are equal to 1600 miles, rounded to the nearest 0.1 km ? c) Every year, monarch butterflies migrate around 3200 km from Canada to Mexico. About how many miles do they migrate, rounded to the nearest 0.1 mi .?

To convert kilometers to miles, use the conversion factor of 1 kilometer being approximately 0.621371 miles. So, if you plug in 1600 km into that nifty formula, you'll find that it rounds to around 993.6 miles. Isn't it interesting how these butterflies travel such enormous distances, proving that nature is purposeful in its design? Flip the script for miles to kilometers, where 1 mile is about 1.60934 kilometers. Thus, if we take 1600 miles and work that out, we end up with approximately 2574.1 kilometers! Now, if you're envisioning the grand journey of those monarch butterflies, this year, they’ll be flapping their wings over 3200 kilometers, which translates to about 1988.8 miles.
