Sarah is selling cupcakes. During rush hour (3pm-6pm) she got lots of business, for 3 hours. She sold 20 cupcakes at a slow steady rate until 6:00pm. It started to get late and her cupcake sales declined at a slow steady rate, for another 3 hours. She only sold 5 cupcakes between 6:00-9:00pm. Once it was 9:00pm nobody came, for 4 hours. This is why there is a straight horizontal from 9:00pm-1:00am. She then packed up her stuff and went to bed.
