You can calculate

825 miles / 200000 km

in a Google search box, and it yields about 0.006638 -- or about 6.6 msec.

You're dividing an imperial distance measurement, by a metric one... [200K KM == 124 274.238 miles](http://www.google.ca/search?hl=en&safe=active&client=firefox-a&hs=q5W&rls=org.mozilla%3Aen-US%3Aofficial&q=200000+km+to+miles&aq=f&aqi=&aql=&oq=&gs_rfai=) – OMG Ponies Jun 22 '10 at 22:18

If there is 5.0 × 10^-9 s / m delay and if 825 miles are equivalent to 1,327,708.8 meters then the delay will be (5*10^-9)*1327708.8 or 0.006638544 seconds

1 (sec) / 200,000 (KM) = 0.000005 (s / km)

1.609344 (mile in KM) x 825 = 1327.7088 KM

Therefore the delay over 825 miles is 0.006638544 seconds.
