FIND THE ELAPSED TIME

START 1:43
FINISH 6:20

HOW DO I FIND IT

6:30 - 1:43

You need to change 6:30 to 5:90 then subtract.

5:90 - 1:43 = ?

We'll be glad to check your answer.

4 HR AND 47 MIN, WHAT I DON'T UNDERSTAND IS WHY DO I CHANGE 6:30 to 5:90, thank you Ms.Sue

You're welcome. Your answer is right. :-)

The easiest way to subtract 1:43 from 6:30 is to change 6:30 to 5:90 because you can't take 43 from 30 without borrowing.

Thirty minutes after six is the same as 90 minutes after five.

To find the elapsed time between the start time and finish time, you can follow these steps:

Step 1: Convert the start and finish times into a common format. In this case, both times are already in a 12-hour format.

Step 2: Separate the hours and minutes in both the start and finish times. For the given example:

Start Time: 1:43
Finish Time: 6:20

Step 3: Calculate the time difference between the start and finish times. Start by subtracting the hours:

6 - 1 = 5

Next, subtract the minutes. Since the finish minute is smaller than the start minute, you need to borrow an hour:

(60 + 20) - 43 = 37

Step 4: Combine the hours and minutes to get the elapsed time:

Elapsed time = 5 hours and 37 minutes

Therefore, the elapsed time between 1:43 and 6:20 is 5 hours and 37 minutes.
