AP Precalculus 1.1-1.3

Which of the following scenarios would best represent the graph shown?

• Jackson ran to try and catch a bus at a stop near his house. He waited two minutes at the stop but realized he had missed the bus. So he slowly walked home.

• Wesley walked to the end of his driveway to get the newspaper and then turned to walk back inside at the same constant rate.

• Ben walked to a gas station close to his home to get a soda. He talked to some friends at the gas station for a few minutes. His mom called and told him to get home to do his Precal HW. The friend drove Ben back home. Luckily he got home faster in the car than when he walked.

• Jenny and her friend took the escalator to the 2nd story of the mall, shopped there for a while, and took the escalator back down.
