Ijust need someone to check my answer.
jocelyn needs to study two stars for her astronomy research. she has narrowed her choices down to four stars that are located on a straight line from earth. jocelyn wants to study the two stars that are closest to each other. which two stars should she study?
and here i solved them
star a | 0.176 * 10^18 km 176
star b | 22.1310^16 km 2213
star c | 314210^14 km 3142
star d | 125.510^15 km 1255
i chose a and d.
it then also asks
"what is the distance between the two stars? explain your strategy"
and i put "i solved the answers and once i got the numbers closest to each other i subtracted them to get 505"

if i'm wrong can you correct my mistakes?
