This topic focuses on practicing calculating which of two moving objects travels a greater distance, considering different speeds and time durations. It also involves working with various units of measurements for both speed (e.g., cm/min, mm/min, m/ms, cm/s, cm/hr) and time (e.g., min, hr, ms, s, d). Each problem poses a scenario with two objects moving at different rates and over different periods, challenging the learner to convert units where necessary and determine which object covers a longer distance.
