Question

Light travels at a speed of 3.0 ´ 108 m/s. If it takes light from the sun 5.0 ´ 102 s to reach Earth, what is the distance between Earth and the sun?

Answer 1

You have velocity and time and need to find distance. What formula relates all these?:
\[v = \frac{ d }{ t }\]
Rearrange for d and you should be set!

Answer 2

distance = speed * time u have already been given the speed and time. just plug in those values..that's it! got it? @Phoebe_tea

Answer 3

thank you guys. I dont know who to give the medal to though aha >.<
