if it is sunday, 4:50 p.m.,what will the day and time be 20 1/2 hours later?

well, 24 hours later it will be Mon 4:50 pm

20 1/2 is 24 - 3 1/2

4:50 - 3:30 = 1:20 pm Monday

24 hours later will be 4:50 PM on Monday. What would be 3.5 hours earlier?

To determine the day and time 20 1/2 hours later, we need to add 20 1/2 hours to the current time of Sunday, 4:50 p.m.

To add 20 1/2 hours, we can first convert 1/2 hour into minutes. Since 1 hour has 60 minutes, 1/2 hour is equal to 30 minutes. Therefore, we now need to add 20 hours and 30 minutes to 4:50 p.m.

Adding 20 hours to 4:50 p.m. will give us 24 hours, which means the day will change. Since Sunday is the current day, 20 hours later will be Monday.

Now, adding the remaining 30 minutes to the new day, Monday, we get the final time. 4:50 p.m. + 20 hours + 30 minutes equals 1:20 p.m. on Monday.

So, the day and time 20 1/2 hours later will be Monday, 1:20 p.m.
