In the United States, most trains operate at a top speed of 100 miles per hour. Scholars use information on the distance and time of a train trip to determine if the train ever reaches a specific speed. They connect pieces of information to reverse solve formulas and equations.
- Connect the lesson to probability as well as geometry concepts
- Have pupils list the maximum and minimum possible values for the speed
- Relies on prior knowledge of problem-solving strategies and rate formulas
- Applies mathematical problem solving to real-life situations
- Multiple methods work to solve the problem
