Question

The light from sun takes 8.33 minute to reach Earth . calculate the distance between sun and earth.


​

Answer 1

Given that,

• Time = 8.33 minutes = 510 seconds

• Speed of light = 300000 km/s

• Distance = ?

we know that,

⇒ Distance = speed× Time

⇒ Distance = 300000 km/s × 510 seconds

⇒ Distance = 153000000

⇒ Distance = 1.53×$10^{8}$ km

Therefore, the distance between earth and the sun is  1.53×$10^{8}$ km (approximately).

Hope this helps you.

Answer 2

Answer:

T=8.33 min

=8.33×60second

speed=3×10^8m/seconds

Distance= speed ×time

3×10^8×8.33/100×60

=8.33×18×10^7

=1.4994×10^7

=1.4994×10^11
