Elapsed Time Within the Hour: End-Time-Unknown 3-126
Use a timeline to solve elapsed time problems by visualizing the start time, elapsed time, and end time. Start by finding the end time – result unknown problems – when the end time and start time are within the same hour. If the start time is 1:08 and elapsed time is :17, what is the end time? It's 1:08 + :17 = 1:25.
