Answer
(a) $1~light~second = 3.0 \times 10^8~m$
(b) $v = 1 ~light~second~per~second$
Work Step by Step
(a) We can find the distance light travels in one second:
$d = v~t$
$d = (3.0\times 10^8~m/s)(1.0~s)$
$d =3.0\times 10^8~m$
$1~light~second = 3.0 \times 10^8~m$
(b) We can find the speed of light:
$v = \frac{distance}{time}$
$v = \frac{1~light~second}{1~second}$
$v = 1 ~light~second~per~second$
