<PRE><B>Question 214753</B>
Electricity travels at 186,000 mi/s. How far does electricity travel in
200 ps? Give your answer in inches.


Step 1.  200 picoseconds = {{{200*10^(-12)}}} seconds = {{{2*10^(-10)}}} seconds


Step 2.  (186,000 miles/sec)*(5280 feet/mile)*(12 inch/feet)*2*10^(-10) sec = 2.357 inches.


I hope the above steps were helpful.
