Partner Practice: 1. Charlene heads out to school by foot on a fine spring day. Her distance from school, in blocks, is given as a function of the time, in minutes, she has been walking. This function is represented by the graph given below. (a) How far does Charlene start off from school? (b) What is her distance from school after she has been walking for 4 minutes? (c) After walking for six minutes, Charlene stops to look for her subway pass. How long does she stop for? (d) Charlene then walks to a subway station before heading to school on the subway. How many blocks did she walk to the subway? (e) How long did it take for her to get to school once she got on the train? 2. During a snowstorm, a meteorologist tracks the amount of accumulating snow. For the first three hours of the storm, the snow fell at a constant rate of one inch per hour. The storm then stopped for two hours and then started again at a constant rate of one-half inch per hour for the next four hours. On the grid below, draw and label a graph that models the accumulation of snow over time using the data the meteorologist collected. If the snowstorm started at 6 p.m., how much snow had accumulated by midnight?
