Step-by-step explanation:

Given parameters:

    Number that rode in columns = times the number that rode in rows.

Unknown:

Number of people that rode in rows = ?

Solution:

   Let the number of people that rode in rows  = R

                 C = R

Number of people that rode in rows  = 2200;

            2200 =  R

             11R  = 2200 x 3

                R  =

                R = 200 x 3

               R  = 600

Number of people that rode in rows  = 600
