Question

The distance between earth and sun is 15000000km. Light takes 499 seconds to reach earth from sun. Calculate the speed of light from the data provided. Mention the unit as well.

Answer 1

The speed of light is 30,060,120.24048 m/s.

Answer 2

Answer:

15000000 km into m

1 km = 1000m

15000000 km = 15000000 × 1000 m

= 15000000000m

speed = distance travelled / time taken

or, speed = 15000000000/499 m/s

so, speed = 30,060,120.24048m/s
