A fox called Fred spots a rabbit sitting happily nibbling grass 18 meters away. At the same time, the rabbit (called Roger) notices the fox. The fox chases the rabbit who runs in a straight line away from him. Fred can run at 5.5 meters a second. Roger can run at 3.5 meters a second. How long will it take the fox to catch up with the rabbit? Make sure you have evidence to back this up, and use a math problem solving template to explain your thinking. Want a score of a 4?
