X-rays travel at what speed?

  1. 100,000 miles per second

  2. 150,000 miles per second

  3. 186,000 miles per second

  4. 200,000 miles per second

The correct answer is: 186,000 miles per second

X-rays travel at the speed of light, which is approximately 186,000 miles per second. Option A is incorrect because it is too low, and option D is incorrect because it is too high. Option B, while also incorrect, is closer to the correct answer but still falls short. X-rays are a form of electromagnetic radiation, and as such, they travel at the same speed as all other electromagnetic waves, including visible light and radio waves, which is 186,000 miles per second.
