Answer 2

To calculate the given expressions, let's break them down step by step:

1. 2 hours and 35 minutes: To convert this into minutes, we can multiply 2 hours by 60 (since there are 60 minutes in an hour) and then add the remaining 35 minutes. So, 2 hours and 35 minutes is equal to 155 minutes.

2. 3 days, 18 hours, and 20 minutes: To convert this into hours, we can multiply 3 days by 24 (since there are 24 hours in a day), then add the remaining 18 hours, and finally add the 20 minutes converted into hours (20 minutes divided by 60). So, 3 days, 18 hours, and 20 minutes is equal to 90 hours and 20 minutes.

3. 34 seconds and 52 seconds: To calculate the sum of these two values, we simply add them together. So, 34 seconds + 52 seconds is equal to 86 seconds.

Now, let's calculate the results:

1. 2 hours and 35 minutes is equal to 155 minutes. 2. 3 days, 18 hours, and 20 minutes is equal to 90 hours and 20 minutes. 3. 34 seconds and 52 seconds is equal to 86 seconds.
