If Jupiter exploded at this very instant, how long until we know about it? Briefly support your answer.

Explanation:

Jupiter is 661.53 million km(A) away from earth. Light travels at 299,792 kilometers per second(B). Calculate the answer by dividing A from B. Use the speed distance time triangle.

You know the distance from earth to Jupiter and you know the speed that the light would travel (There is no sound in space,as it is an empty vacuum) so you can calculate it. Show your working.
