At what speed does one knot equate to in miles per hour?

One knot is defined as one nautical mile per hour. To convert knots to miles per hour, it's important to know that a nautical mile is approximately 1.15078 statute miles. Therefore, when you convert 1 knot to miles per hour, you multiply by this conversion factor.

Calculating this gives you approximately 1.15 miles per hour. This is why the answer that corresponds to this conversion is correct. Understanding this conversion is essential in aviation, as flight speeds are often represented in knots, and being able to interpret those speeds in more familiar units like miles per hour can be helpful for various operational and communication needs.

The other options do not align with the conversion factor from nautical miles to statute miles, which is why those choices wouldn't be correct.
