Scarlet maintained a constant speed throughout
her 7-hour journey. Her speed can be modeled
by 455 = mx, where x is the time in hours, and m
is the rate at which Scarlet traveled.
Based upon these two models, which person
traveled at a greater speed? Explain your
reasoning by using a written description each
scenario. Be sure to include the unit rates in your
explanation
