You fly 120 NM at 160 knots. How long will the flight take?

Explanation:
The main idea is the relationship between distance, speed, and time: time equals distance divided by speed. With speed in knots, you’re traveling nautical miles per hour, so 120 NM at 160 knots means time = 120 ÷ 160 hours = 0.75 hours. Convert to minutes: 0.75 × 60 = 45 minutes. So the flight takes 45 minutes. (As a quick check, at 160 knots you cover 40 NM in 15 minutes, 80 NM in 30 minutes, and 120 NM in 45 minutes.)
