Question

The speed of light is 3 x 105 kilometers/second.

If the sun is 1.5 x 108 kilometers from Earth,
how many seconds does it take light to reach the Earth?

Answer 1

Speed = Distance / Time
Time = Distance / Speed
Time = (1.5 * 10^8) / ( 3 * 10^5 )
Time = 1/2 * 10^3
Time = 500 seconds
1 minute = 60 seconds
500 seconds = 8 minutes 20 seconds

Answer 2

Answer:

Explanation:

Speed = Distance / Time

Time = Distance / Speed

Time = (1.5× 10^8) / ( 3 ×10^5 )

Time = 1/2 × 10^3

Time = 500 seconds

1 minute = 60 seconds

it reach at 8min 20 sec
