Do the same process for each of the 3
you have miles per how many minutes and you need miles per hour
you know 60 minutes make 1 hour convert the minutes to hours
this will gives you miles per equivalent hour
you need miles per 1 hour
Here is number 1
1) 5 miles in 20 minutes
5 miles in (20/60) hr = 5 miles in 1/3 hr
to get 1 hr multiply by 3
equation so keep the balance
5 * 3 = 15
rate = 15 miles per hour.
same process for the others

Answer:
Star B
Step-by-step explanation:
If Star A is 5.23*10^7 light years away from earth, and star B is 7.1*10^5 light years away from earth, then the closest Star to earth is Star B.
this is because a light year is 9.461*10^15 m away, if we multiply this, then Star A is 4.948*10^23 m away from earth, and Star B is 6.717*10^21 m away from earth, and this makes it closer when compared to Star A.
