- 6. It takes Mary 15 minutes to drive to school and her route is 18km long. What is Mary's average speed on her drive to school in units of m/s?3. Bob wanted to reach the peak of a mountain. He started at the base and started driving a car towards the peak of the mountain. The car started at 0 mph and the speed increased over time to 40 mph. Halfway towards the peak of the mountain, the terrain became too rugged and Bob instantly stopped his car to analyze the terrain. After spending time observing the terrain, Bob decided to instantly climb the rocky terrain at a slow pace. Once Bob passed the rocky terrain he realized his shins were cut up so he immediately travelled back to the car at the same slow pace as before. After spending time putting on bandages, he realized there was a side path to the peak of the mountain. He immediately started running to the peak of the mountain and eventually reached the peak. Graph the relationship between Bob’s (a) distance and time and (b) position and time. For the graph, make it clear what part of your function corresponds with his different parts of his travels.
