Chana and Josiah started skating at the same time in the same direction, but Josiah had a head start 10 meters past the starting line. Chana skated 3 meters per second and Josiah skated 2 meters per second. Here's a graph that shows a system of equations for this scenario where x is the number of seconds since Chana and Josiah started skating and y is the distance in meters from the starting line.

A. Chana's distance from the starting line at a time when she is behind Josiah
B. Josiah's distance from the starting line at a time when he is behind Chana
C. Chana's and Josiah's distance from. the starting line at the time when Chana catches up with Josiah
D. Chana distance from the starting line at a time when she is father than Josiah
