Interactive step-by-step solver for understanding time concepts including reading clocks, time conversion, elapsed time, and solving time-related word problems.
Step 6: Therefore, 4 hours and 20 minutes is equal to 260 minutes.
Example 2: Calculating Elapsed Time
How much time passes between 9:15 AM and 11:45 AM?
Step 1: Identify the start time (9:15 AM) and the end time (11:45 AM).
Step 2: Calculate the difference in hours. From 9:00 AM to 11:00 AM is 2 hours.
Step 3: Calculate the difference in minutes. From 9:15 AM to 9:45 AM is 30 minutes. From 9:45 AM to 10:45 AM is 1 hour. From 10:45 AM to 11:45 AM is 1 hour.
Step 4: Another way to calculate is to subtract the start time from the end time.
Subtract the minutes: 45 minutes - 15 minutes = 30 minutes.
Subtract the hours: 11 hours - 9 hours = 2 hours.
Step 5: Combine the hours and minutes differences. The elapsed time is 2 hours and 30 minutes.
Step 6: Therefore, 2 hours and 30 minutes pass between 9:15 AM and 11:45 AM.
Example 3: Time Word Problem (Finding End Time)
A train departs at 6:30 PM and the journey takes 3 hours and 45 minutes. What time will the train arrive?
Step 1: Identify the start time (6:30 PM) and the duration of the journey (3 hours and 45 minutes).
Step 2: Add the hours to the start time. 6:30 PM + 3 hours = 9:30 PM.
Step 3: Add the minutes to the current time (9:30 PM). 9:30 PM + 45 minutes.
Step 4: Adding 30 minutes to 9:30 PM takes us to 10:00 PM.
Step 5: We have 15 minutes remaining (45 - 30 = 15). Add the remaining 15 minutes to 10:00 PM.
10:00 PM + 15 minutes = 10:15 PM.
Step 6: Therefore, the train will arrive at 10:15 PM.
