Jodied to run for exercise. To warm up, she walked at a constant speed for a distance of 100 min 100 s Then she increased her speed to 4 ms she ran at this speed for 5 min (300 s. At that point she began going up a steep it and her speed dropped back to 1 m/s. It took her 4 min (240 s) to reach the top of the him. At that time she stopped and rested for 3 min before continuing her run Construct a distance-time graph and a speed time graph of Jodi's motion Label the axes Then explain what is being shown as the slope of each Distance-Time Graph Speed-Time Graph
