The time-distance graph shows Carol walking at a steady rate. Her partner used a motion sensor to measure her distance from a given point. a. According to the graph, how much time did Carol spend walking? b. Was Carol walking toward or away from the motion sensor? Explain your thinking. c. Approximately how far away from the motion sensor was she when she started walking? d. If you know Carol is 2.9 m away from the motion sensor after 4 s, how fast was she walking? e. If the equipment will measure distances only up to 6 m, how many seconds of data can be collected if Carol continues walking at the same rate? f. Looking only at the graph, how do you know that Carol was neither speeding up nor slowing down during her walk?
