First of all, lets do the n part. WE have -5.1n-3n which equals -8.1n. Then, we have 3.2+5, which is 8.2. So we have 8.2-8n or -8.1n+8.2

The average distance from the Sun to the Earth is 1.5 × 10^11 meters and the speed of light is 3 × 10^8. If distance = rate times time, how many seconds on average does it take for the Sun's light to reach Earth?

Answers

Answer:

1.503⋅10^11

light years

The time taken for the Sun's light to reach Earth is t = 5 x 10² seconds

What is Speed?

Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude

Speed = Distance / Time

Given data ,

Let the speed be represented as S

Now , the value of S is

S = D / T

where , the distance D = 1.5 × 10¹¹ meters

S = 3 × 10⁸ m/s

And , T = D / S

On simplifying , we get

Time taken T = 1.5 × 10¹¹ / 3 × 10⁸

T = 0.5 x 10³

T = 5 x 10² seconds

Hence , the time taken is T = 500 seconds
