The function d(t)=300,000t represents the distance (in kilometers) that light travels in t seconds.

a. how far does light travel in 15 seconds?

kilometers

b. how long does it take light to travel 12 million kilometers?

seconds.

If the function d(t)=300,000t represents the distance (in kilometers) that light travels in t seconds.

The light travels  4500000 kilometers in 15 minutes

It takes the light 40 seconds to travel 12 million kilometers

The given function is:

d(t)  =  300000t

where d represents the distance (in kilometers)

t represents the time traveled (in seconds)

To get the distance traveled by the light in 15 seconds, substitute t = 15 into the function d(t)  =  300000t

d(15)  =  300000(15)

d(15)  =  4500000 kilometers

The light travels  4500000 kilometers in 15 minutes

To get the time taken for the light to travel 12 million kilometers, substitute d(t) = 12000000 into the function d(t)  =  300000t and solve for t.

d(t)  =  300000t

12000000  =  300000t

t  =  12000000 / 300000

t  =   40 seconds

It takes the light 40 seconds to travel 12 million kilometers

a. The light travels 4,500,000 kilometers in 15 seconds

b. It takes the light 40 seconds to travel 12 million kilometers

Step-by-step explanation:

- The function d(t) = 300,000 t represents the distance in kilometers

  that light travel in t seconds

a.

- We need to find how far the light travels in 15 seconds

∵ d(t) = 300,000 t

∵ t = 15 seconds

- Substitute the value of t in the function above

∴ d(t) = 300,000 (15)

∴ d(t) = 4,500,000 kilometers

The light travels 4,500,000 kilometers in 15 seconds

b.

- We need to find how long does it takes the light to travel 12 million

  kilometers

∵ d(t) = 12 million kilometers = 12,000,000 km

∵ d(t) = 300,000 t

- Substitute the value of d(t) in the function

∴ 12,000,000 = 300,000 t

- Divide both sides by 300,000

∴ t = 40 seconds

It takes the light 40 seconds to travel 12 million kilometers
