Time Calculation and Problem Solving

The video tutorial teaches how to solve word problems involving time using diagrams. It explains how to read clocks, count minutes, and use timelines to calculate time-related problems. Two examples are provided: determining Sarah's departure time to reach her friend's house by 3:15 PM and calculating Michael's available time before his school bus arrives at 8 AM.

• 1:15 PM

• 1:45 PM

• 2:15 PM

• 2:00 PM
