Ruby and Will are running a team relay race. Will runs twice as far as Ruby. Together they run 18 miles. How far did each person run?

Respuesta :

first you start thinking of things that add up to 18
9 and 9? no because they would both be equal
so start thinking of thinks that might work, and you will find that 
6+12 is 18!
6= ruby
6x2=will
6x2=12

ruby ran 6 miles and will ran 12.

hope this helps

ruby ran 6 ran 12 because if you add 6 and 12 you get 18
