Elapsed Time Bridge the Hour: Elapsed-Time-Unknown 3-130

Find the elapsed time – change unknown problems – when the end and start times are in different hours. If the start time is 2:48 and the end time is 3:14, what is the elapsed time? First add :12 to get to 3:00. Need to add :14 more to get to 3:14, so the total elapsed time is :12 + :14 = :26. 2:48 + :26 = 3:14.
