🔍 Key Concepts

• Speed of radio waves / light in air is approximately 162,000 nautical miles per second • RADAR range equations use a "there and back" (outbound + return) distance • Convert seconds to microseconds carefully (1 second = 1,000,000 microseconds)

💭 Think About

• First, calculate the total distance the pulse travels when it goes to the target and back, in nautical miles • Use the speed of propagation to find the time in seconds: time = distance / speed • Convert that time from seconds into microseconds and compare with the answer choices

✅ Before You Answer

• Be sure you used 20 NM, not 10 NM, for the total travel distance • Confirm that you used nautical miles per second, not knots or miles per hour • Double‑check your seconds to microseconds conversion before picking the closest option
