Multiple Choice

According to the 3 minute rule, the distance covered in 3 minutes at 100 knots is expressed in which unit?

In navigation, speeds are in knots (nautical miles per hour), so distances over a short interval are expressed in nautical miles. Use the formula distance = speed × time. Three minutes is 0.05 hours, so at 100 knots the distance is 100 × 0.05 = 5 nautical miles. Therefore the distance covered is 5 nautical miles. The other units (meters, feet, yards) are not used here because they don’t align with speed given in knots.
