The function d(t)= 300,000t represents the distance (in kilometers) that light travels t seconds How long does it take light to travel 12 million kilometers?

Respuesta :

The function for the distance travelled is d(t) = 300,000t.

Determine the time taken by light to travel 12 million km.

[tex]\begin{gathered} 12000000=300000\cdot t \\ t=\frac{12000000}{300000} \\ =\frac{120}{3} \\ =40 \end{gathered}[/tex]

So light takes 40 seconds to travell 12 million km.

Answer: 40 seconds
