It is possible to find the rate of change for an interval between two points of a function by finding the slope between the points. use the graph to find the y-value for each x-value. then find the rate of change for each interval.

Me with this assignment ! i only partially understand, so explain. also it's a work sample. at the championship bike race, steve and paula were fighting for first place. steve was 175 feet ahead of paula and had only 300 feet left to go. he was very tired and was going only 9 feet per second. paula was desperate to catch up and was going 15 feet per second. who won the bike race and by how far did she/he win?
