Final answer:
Building codes typically specify that a stairway should not exceed a vertical rise of 12 feet between floor levels or landings. Dimensions such as step width and height are regulated for safety and can be used to calculate the distance covered on a staircase.
Step-by-step explanation:
A stairway should not have a vertical rise larger than 12 feet between floor levels or landings. Building codes often regulate the dimensions of staircases for safety and accessibility reasons.
The information given about step width and height can be used to calculate the number of steps and the total rise of the staircase if necessary. In this example, with a step width of 20 cm and a step height of 15 cm, a jogger covers a significant distance along the stairs, which we calculate by considering the total steps taken.
