A rocket is scheduled to launch from a command center in 3.75 hours. The launch time is at 11:20 AM. What time is it now?

Answer :

The current time is 7:35 AM. This is calculated by subtracting the time difference (3.75 hours) from the given future time (11:20 AM).

This problem involves calculating the current time based on the given future time (11:20 AM) and the difference between now and the future time (3.75 hours).

To solve this, we subtract 3.75 hours from 11:20 AM.

The first step in this subtraction is to convert 3.75 hours to hours and minutes.

The decimal .75 represents 3/4 of an hour, which is equivalent to 45 minutes.

So, we need to subtract 3 hours and 45 minutes from 11:20 AM.

Subtracting the minutes, 20 minutes - 45 minutes, is not possible without borrowing, so we borrow 1 hour from the hours. This makes it 10 hours and 80 minutes.

Now, we can subtract: 80 minutes - 45 minutes equals 35 minutes. Then subtract the hours: 10 hours - 3 hours equals 7 hours.

So, the current time is 7:35 AM.
