Question

The speed of light is about 300,000 kilometers per second. The Sun is about 93 million miles from Earth. How many minutes does it take for the sunlight to reach Earth? Round to the nearest tenth if necessary.

Answer 1

Answer: 8.3 minutes

Step-by-step explanation:

1 mile is to 1.60934km so 93 million miles is:

= 93 * 1.609

= ‭149,637,000‬ km

Travelling at 300,000 km per second, the number of seconds it takes is:

= ‭149,637,000‬/300,000

= ‭498.79‬ secs

In minutes this is:

= ‭498.79‬/60

= 8.3 minutes
