If your groundspeed is 480 knots, how many miles per minute are you traveling?

To determine how many miles per minute you are traveling at a groundspeed of 480 knots, you need to understand the conversion between knots and miles per minute. A knot is defined as one nautical mile per hour.

Since there are 60 minutes in an hour, to convert knots to miles per minute, you can use the following conversion:

1. First, note that 1 knot is equivalent to about 1.15078 miles per hour.

2. Therefore, to convert the speed in knots into miles per minute, you can multiply the speed in knots by the conversion factor and then divide by 60 (since there are 60 minutes in an hour).

Following this:

480 knots × 1.15078 miles/knot = 552.3744 miles per hour.

Now, convert miles per hour to miles per minute:

552.3744 miles per hour ÷ 60 minutes/hour = 9.13957 miles per minute.

Rounding this to a reasonable figure gives roughly 9 miles per minute. This is why the correct answer is 9 miles per minute.

Understanding this conversion is essential in aviation as it helps in calculating the time it takes to reach a destination based on the groundspeed and distance.
