This math topic focuses on advanced problems related to speed, distance, and time, specifically comparing two cars that travel for the same duration but at different speeds. Students are required to calculate the speed of the second car given the speed of the first car and the distance difference between them. The problems are designed to enhance students' abilities to manipulate the fundamental formula: speed = distance/time and apply algebraic skills to solve for unknowns in word problems related to real-life scenarios of moving vehicles.
