i have two questions 1)7,000,000 picoseconds how many microseconds 2) determine how far electricty travels in 7 microseconds. express your answer in miles. I do not want the answer to either question, I just need to know how to do the equations. Thank you.

1 million picoseconds = 1 microsecond

All electromagnetic radiation, including light, radio transmission and electricity, travels at approximately 186,000 miles (300,000 kilometers) per second; more than seven times around the equator in one second. More precisely, the speed is 299,792,458 meters per second in a vacuum.

Does that help?

on the first question it helps a ton on the second question no, I am not sure how to write the equation for the second one in order to figure out the problem.
Answered by PsyDAG
186,000 * 7 microseconds = ?

1 microsecond = one millionth of a second.

Does that help a little more?
