This math topic involves problems designed to practice calculating speeds under different scenarios where two cars travel the same distance but arrive at different times. It challenges learners to compute the speed of one car based on the speed of another and the time difference in their arrivals. Each problem provides multiple-choice answers to select the correct speed of Car B, given varying distances, the speed of Car A, and the time delta between the two cars. This set of problems is part of an advanced unit on speed, distance, and time.
