Answer

Explanation:

Step1: Convert 5 minutes to seconds

Since 1 minute = 60 seconds, then 5 minutes = 5×60 = 300 seconds.

Step2: Use the formula distance = speed×time

The speed of light is $v = 3.0\times10^{8}$ km/s and the time $t = 300$ s. So the distance $d=v\times t=(3.0\times 10^{8})\times300$. $d=(3.0\times 10^{8})\times(3\times10^{2})=(3.0\times3)\times(10^{8}\times10^{2}) = 9.0\times10^{10}$ km.

Answer:

C. $9.0\times 10^{10}$ km
