Light travels at a speed of 3×108 m/s. It takes light 8 minutes to reach the Earth from the Sun. Assuming Earth’s orbit is a circle, find x if the speed with which the Earth is moving around the Sun in km/h is x×104km/hr.

The exact time taken by light to reach the Earth from Sun is 8 minutes and 20 seconds i.e. total 500 seconds.

Speed of light in vacuum is 3∗1083∗108 m/s.

speed=distancetimespeed=distancetime

distance=speed∗timedistance=speed∗time

distance=3∗108∗500distance=3∗108∗500

gives you 
distance=150,000,000,000distance=150,000,000,000 meters

or 150,000,000150,000,000 kilometers.

Obviously, these are not scientifically accurate calculations. The time will not be exactly correct and distance beteween earth and sun is going to change as earth revolves in elliptical orbit.
