We were given the distance, d as a function of time, t.

d(t)=300,000t.

To find d(15), we put t=15, in to


d(t)=300,000t


This implies that,

d(15)=300,000(15)


d(15)=4,500,000

This means that in 15 seconds light covers a distance of 4,500,000 kilometers

Answer:

d(15)=4,500,000 kilometers

Step-by-step explanation:

The distance traversed by a beam of light is represented as a function of time:

d(t)=300,000 t

This function represents distance traveled by the light in 't' seconds.

Now d(15) means, how much distance will the light beam cover in 15 seconds.

Putting t=15 in the function will tell us the distance traveled by light in 15 seconds.

d(15)= 300,000 \times t=300,000\times 15=4,500,000

So basically light has traveled, 4.5 million kilometers in 15 seconds.
