Question

If a bit is travelling through a copper wire at 2 x 10 8 meters per second, how far does it go in a millisecond?

Answer 1

Answer:

$2\times10^5$m

Explanation:

1 second = 1000 millisecond, so if within 1 second a bit could travel a distance of $2\times10^8$m through a copper wire then within a millisecond (a thousandth of a second) it should be able to travel through a distance of

$\frac{2\times10^8}{1000} = 2\times10^5$m
