You are flying 180 knots. How long will it take to travel 45 NM?

• A. 5 minutes
• B. 10 minutes
• C. 20 minutes
• D. 15 minutes

Answer: (D)

Time to travel is found by dividing the distance by the speed. At 180 knots, you cover 180 nautical miles in one hour. For 45 nautical miles, time equals 45 ÷ 180 hours, which is 0.25 hours. Converting to minutes gives 0.25 × 60 = 15 minutes. A quick check: 45 is a quarter of 180, so it takes a quarter of an hour—15 minutes—to cover that distance at this speed. For quick context, 5 minutes would cover about 15 NM, 10 minutes about 30 NM, and 20 minutes about 60 NM, so 45 NM fits with 15 minutes.
