Learn to tell how much time has passed (elapsed) in minutes.

Look at the
two clocks below.

The clock above reads 8:15.

The clock above reads 8:30.

The difference between 8:15 and 8:30 is 15 minutes.

From 8:15 to 8:30 is 15
minutes because 30 -15 = 15. Because the hours are the same, you only need to
subtract the minutes to find the difference.

Look at the two clocks below.

The clock above reads 1:24.

The clock above reads 1:49.

To find the difference (the minutes that passed) between 1:49 and 1:24 you need to subtract the minutes.

49
- 24 = 25.

There is a 25 minute difference between 1:24 and 1:49.

When the hours are different, you need to subtract and add. Look at the clocks
below.

The clock above reads 4:33.

The clock above reads 5:11.

You will need to do this problem in two steps.

First, find how many minutes it is
until 5:00. To do this, subtract 33 minutes from 60 minutes.

60 - 33 = 27.

Next, add the 11 minutes past 5:00. This is the difference between 5:00 and
5:11.

27 + 11 = 38

The difference between 4:33 and 5:11 is 38 minutes.

Complete the problems below.

The time is 1:05

The time is 1:10.

The difference between 1:05 and 1:10 is minutes.

The time is 1:10.

The time is 1:30

The difference between 1:10 and 1:30 is minutes.

The time is 2:26.

The time is 2:41.

The difference between 2:26 and 2:41 is minutes.

The difference between the clocks above is minutes.
