If you travel 300 NM at 150 knots, how long does it take?

• A. 3 hours
• B. 1.5 hours
• C. 2 hours
• D. 2.5 hours

Answer: (C)

Time equals distance divided by speed when speed is in knots and distance in nautical miles. At 150 knots, you cover 150 NM in one hour. For 300 NM, time = 300 ÷ 150 = 2 hours. So the trip takes 2 hours. (3 hours would need 450 NM, 1.5 hours would be 225 NM, and 2.5 hours would be 375 NM.)
