Question

Light travels 300,000 km/s. The planet Mars is about 228,000,000 km from the sun. How would you find out how many minutes it takes light from the Sun to reach Mars?

Answer 1

12.67 minutes

Explanation:

Time taken is given by distance divided by speed

Given distance of 228, 000, 000 km and speed of light as 300, 000 km/s then time will be

Time=228, 000, 000/300, 000=760 seconds

Conversion

60 seconds make up 1 minute

760 seconds will be 760/60

Time=760/60=12.666666666666

Rounded off, this is 12.67 minutes
