<PRE><B>Question 909964</B>
light travels at a rate of 1.86 times 10 to the fifth power. if the distance from a star to a planet in its orbit is 80 million miles,find how long it takes the light of the star to reach the planet.
--------------
time = distance/rate
-----
time = (80*10^6 miles)/(1.86*10^5 miles/sec) = 43*10 
= 430.1075 seconds  
= 7.167 minutes
