Chana and Josiah started skating at the same time in the same direction, but Josiah had a head start
10
1010 meters past the starting line. Chana skated
3
33 meters per second and Josiah skated
2
22 meters per second.
Here's a graph that shows a system of equations for this scenario where
x
xx is the number of seconds since Chana and Josiah started skating and
y
yy is the distance in meters from the starting line.
