Sarah is on her way to another school trip and the teacher doesn't want anyone to have any fun on the way. She's not allowed to even sit next to her friends on the school bus! Instead she has to sit next to an annoying teacher's pet from her class. Can you help Sarah to speed up her journey, or will she end up with a flat tire?
