Stark’s private jet taxis to the runway and takes off. It climbs steadily to 30,000 feet where it flies for about an hour. The plane then climbs rapidly to 40,000 feet to avoid a storm. The plane descends to 30,000 feet after passing the storm. Finally, the plane descends 15,000 feet and travels at this new altitude until it descends steadily and lands. Which graph best displays Stark’s flight?

Kate drove home after spending a holiday with family. Initially, she drove at a constant speed. Then she stops to shop at an outlet mall. Finally, she drives at a faster constant speed to finish her trip home. Which graph best represents this situation if x is the time in minutes, and y is Kate’s distance from home in miles?
