This math topic focuses on calculating elapsed time with negative changes, as well as converting hours and minutes into clock time for quarter-hour increments. Students are required to determine how a given amount of passed time affects a displayed initial clock time. The problems are set up with multiple-choice answers, challenging students to calculate backward or forward in time and interpret clock faces to select the correct option. This set of problems is a component of a broader unit on practicing negative elapsed time.
