The distance that light travels in 1 year (a light year) is 5.88x10^12 miles. If a star is 2.4x10^8 light years away, what is the distance to that star in miles? Answer in standard notation.

I put the answer 141120000000000000000 miles and it says I'm wrong. Can someone explain to me the right answer?

I put the answer 1.4112 * 10E21 not 1.4112 * 10E20.
