Question

Jessica, Cheryl, Jennifer, and Tricia are standing in line, in that order, with Jennifer halfway between Jessica and Tricia. If the distance between Jessica and Cheryl is 3 feet, and the distance between Jennifer and Tricia is twice the distance between Jennifer and Cheryl, what equation can I use to solve for x

Answer 1

 

 

Jessica             Cheryl                  Jennifer                                  Tricia

 

                 3                                                            6

 

 

x is distance between Cheryl  and Jennifer

 

3+x = 6

 

x = 3
