This math topic focuses on calculating elapsed time by subtracting minutes from given times. It reinforces understanding of how time changes when minutes are subtracted, involving scenarios where the subtraction could cross into previous hours or a new day. The problems make use of quarter-hour increments and expect students to determine what the new time will be after the subtraction. This requires strong comprehension of time-management and some basic arithmetic skills. Each question presents a different challenge with varying amounts of minutes to subtract, aiming to build skills progressively.
