Question 263089
if the speed of light is 3.00 c 10^8m/sec,
 how long does it take light to travel 2.29 * 10^11m, the distance from the sun to Mars?
 Round to one decimal place.
:
Divide dist by the speed of light
{{{2.29(10^11)/3(10^8)}}} = {{{.7633(10^(11-8))}}} = {{{.7633(10^3)}}} = 763.3 seconds
