This math topic focuses on problems involving speed, distance, and time. It specifically challenges students to solve for the speed of a train given certain conditions: a person walking from the back to the front of various lengths of trains, over varying amounts of time, and at different speeds relative to the ground. Each question presents multiple-choice answers, requiring an understanding of relative motion and basic speed-distance-time calculations. This forms part of an introductory logic challenges unit on these concepts.
