Question

Answer 1

2:40PM

Step-by-step explanation:

Let's break down what 80 minutes is:

60 minutes is an hour

Formula: 60 minutes = 1 hour

1 hour plus 20 minutes equals to 1 hour and 20 minutes, also known as:

80 minutes!

--------------------------------------------------------------------------------------------------------------

To do this problem you need to subtract 4:00PM and 80 minutes.

Step-by-step:

If 80 minutes is 1 hour, and 20 minutes let's subtract 1 hour from 4:00PM:

1 hour minus 4:00PM is 3:00PM.

The remaining minutes we have are 20 minutes:

3:00PM minus 20 minutes is 2:40PM!

Formula:

4:00PM - 80 = 2:40PM

Written Formula:

If we subtract 4:00PM and 80 minutes (1 hour & 20 minutes), we will get the answer 2:40PM!

Hope this helps!
