Speed - Person in Train - Solve for Train Length (Level 2)

This math topic covers problems related to calculating the length of a train. It involves understanding speeds, including the speed of a person walking through a train and the train's own speed, to determine the distance from the back to the front of the train. Various scenarios are presented where a person travels at different relative speeds to the ground, and the train travels at different speeds. The individual's task is to compute the train's length based on the time it takes for the person to walk from one end of the train to the other.
