This math topic focuses on calculating the arrival time of a car after a journey, requiring an understanding of how to convert distance and speed into time and then adding this travel time to a start time given in hours on a 24-hour clock. The problems involve determining the exact clock time a car will reach its destination after traveling at a specific speed for a certain distance. The learners practice using the formulas for speed, distance, and time calculations, as well as applying arithmetic operations to clock times.
