250,000mi x 1.61km/1mi =402,500 km

But the correct answer is supposed to be 408,500km. Why am I 6000 short?

**DrBob222**, Sunday, October 2, 2011 at 1:44amThe answer in your book/notes must be wrong. Go to google.com and type in "250,000 to km" without the quotation marks and hit the enter button. The answer is 402,336. Your 402,500 km is correct using the 1.61 km/mi factor. Google uses 1.609344 km/mile
