Question 1 of 27070

If the velocity of a radio wave is 186,000 statute miles per second, how many nautical miles does a radar pulse travel in one microsecond?

🔍 Key Concepts

• Relationship between statute miles and nautical miles (NM) • Conversion of microseconds to seconds and use of basic speed-distance-time formula • Remember that radar range is one-way vs. pulse travel distance is out-and-back

💭 Think About

• First convert the speed from statute miles per second into nautical miles per second. What constant ratio between statute and nautical miles should you use? • Next, convert one microsecond into seconds and use the speed-distance-time formula to find how far the wave travels in that time. • Finally, think about whether the question is asking for the total distance the pulse travels (out and back) or just one-way range, and how that affects your number.

✅ Before You Answer

• Be sure you use 1 NM ≈ 1.1508 statute miles (or the equivalent ratio inverted correctly). • Confirm you’ve converted 1 microsecond to the correct fraction of a second before multiplying by speed. • Check if the distance you compute is plausible: should it be a small fraction of a mile or thousands of miles in one microsecond? That will help rule out unrealistic answer choices.
