Full solution

Q. The Shanghai maglev train travels at a speed of 431431 kilometers per hour. Approximately what is the train's speed in miles per hour?\newline( 11 mile ≈1.61 \approx 1.61 kilometers)\newlineChoose 11 answer:\newline(A) 268268\newline(B) 370370\newline(C) 431431\newline(D) 694694
  1. Conversion factor: To convert the speed from kilometers per hour to miles per hour, we use the given conversion factor: 11 mile is approximately equal to 1.611.61 kilometers.
  2. Division calculation: We divide the train's speed in kilometers per hour by the conversion factor to get the speed in miles per hour. The calculation is 431 kilometers per hour431 \text{ kilometers per hour} divided by 1.61 kilometers per mile1.61 \text{ kilometers per mile}.
  3. Result: Performing the division, we get approximately 267.70267.70 miles per hour.
  4. Closest value: Looking at the answer choices, the closest value to our calculation is 268268 miles per hour, which corresponds to choice (A)(A).
