This math topic focuses on calculating the elapsed time between two clocks, specifically determining how much earlier the time shown on the second clock is compared to the first. Students practice converting the time difference into hours and minutes and are given multiple-choice answers to select from. The problems require interpreting visual information from clock faces to solve negative time differences and enhance time-telling skills at an advanced level. This topic forms part of a broader unit on negative elapsed time calculations.
