How far is 30 miles?

Answer 1

One mile is approximately 1.609 km, or 1609 meters. 1 meter is 100 centimeters, and 1 centimeter is 10 millimeters. Each one of these relationships (e.g. 1m = 100cm) is known as a 'conversion factor' and, in math, is written as a fraction (1m/100cm) that equals 1 (since the top equals the bottom). Thus, to convert 30mm to miles, simply multiply 30mm by all of the above conversion factors; in doing so, you are not changing the original value (since all the conversion factors equal 1) but you are changing the units. Be careful to ensure that the factors all cancel out. The calculation is written thusly: (30mm) x (1cm / 10mm) x (1m / 100cm) x (1mi / 1609m). Millimeters, centimeters, and meters all cancel out, leaving us with miles; carrying out the calculation gives us the answer of 1.864 x 10^-5, or 0.00001864 miles.

Answer 2

30 miles is equivalent to approximately 48.3 kilometers or about a 30-40 minute drive depending on traffic conditions.
