1. What time is on the clock?

2. What time will it be in 1 hour and 22 minutes?

3. What time was it 2 hours and 53 minutes ago?

4. What time was it 4 hours and 14 minutes ago?

Answer :

We begin with the current time:

[tex]$$
\text{Current time} = 03:48:26.
$$[/tex]

Step 1. Adding 1 Hour and 22 Minutes

To find the time after 1 hour and 22 minutes, we add 1 hour and then 22 minutes to the current time:

- Adding 1 hour to 03:48:26 gives 04:48:26.
- Adding 22 minutes to 04:48:26 gives 05:10:26.

Thus, the time after 1 hour and 22 minutes is:

[tex]$$
05:10:26.
$$[/tex]

Step 2. Subtracting 2 Hours and 53 Minutes

To determine the time 2 hours and 53 minutes ago, we subtract 2 hours and then 53 minutes from the current time:

- Subtracting 2 hours from 03:48:26 gives 01:48:26.
- Subtracting 53 minutes from 01:48:26 gives 00:55:26.

Thus, 2 hours and 53 minutes ago, the time was:

[tex]$$
00:55:26.
$$[/tex]

Step 3. Subtracting 4 Hours and 14 Minutes

Next, we calculate the time 4 hours and 14 minutes ago:

- Subtracting 4 hours from 03:48:26 results in a time before midnight. In such cases, we "wrap around" to the previous day. Technically, subtracting 4 hours gives −00:11:34, which corresponds to 23:48:26 on the previous day.
- Then, subtracting 14 minutes from 23:48:26 gives 23:34:26.

So, 4 hours and 14 minutes ago, the time was:

[tex]$$
23:34:26.
$$[/tex]

Final Answers:

- The current time is: [tex]$03:48:26$[/tex].
- In 1 hour and 22 minutes, the time will be: [tex]$05:10:26$[/tex].
- 2 hours and 53 minutes ago, the time was: [tex]$00:55:26$[/tex].
- 4 hours and 14 minutes ago, the time was: [tex]$23:34:26$[/tex].
