This math topic focuses on calculating elapsed time with a specific emphasis on subtracting minutes from given times. It covers scenarios where students are asked to find what the time would be after subtracting increments of 15 or 30 minutes from a starting time, with questions presenting this in the context of quarter-hour time measurements. This helps students practice their skills in time calculation, particularly with understanding how the clock changes with the subtraction of minutes.
