Planet A and Planet B both have aliens on them. Planet B exploded and the alien on A saw the explosion 1 second later. Taking distance to be 3 x 10 to the power of 8.
When will the alien on Planet A hear the explosion.

Using
Speed of sound = 333m/s
Speed of light = 3 x 10 to the power of 8

I think it would just be (3x10^8)/333.

(Distance away)/(speed of sound)=(time it takes)

I felt there was something odd with the question, but didn't know what exactly...

You didnt state that the planets were within a vacuum of space :> They could have shared an atmosphere or something xD /graspingtofindaloophole
