It was a nice day here in NC. Jimmy thought it was a good day to go for a bike ride. He started at zero minutes right in front of a hill. As time passed he kept on increasing his speed at a constant rate to get to the top of the hill. At 6min he had reached the top. From 6min-12min his speed decreased at a constant rate because he was tired from biking up the hill. Then from 12min-21min he was riding at a constant speed of 2mph on the sidewalk which was completely flat. At 21min he stopped at Taco Bell and decided to have lunch there.
