Light takes approximately 8.3 minutes to reach the earth from the sun. If the light from another star takes about two hours to reach earth, how much farther is this star from the earth compared to the distance between the sun and earth?
A) 4 times farther
Two hours = 120 minutes. 120 minutes divided by 8.3 minutes is a little less than 15. Therefore, this star is 15 times farther from the earth than the sun.
