Will arrived at his mother's office at 3 P.M. It took him 30 minutes to walk from his home to the mall. He was in the mall for 45 minutes. It then took him 15 minutes to walk to his mother's office. At what time did Will leave home?

45 + 15 = 60 minutes = 1 hour

1 hour and 30 minutes = 1 1/2 hours

3 - 1 1/2 = 1:30 PM

The test Keyshawn's class took finished at 10:00 A.M. The first part of the test took 30 minutes. There was a 15 minute break. The second part of the test also took 30 minutes. At what time did the test start

See my answer to your later post.

To determine at what time Will left home, we need to add up the time he spent walking from his home to the mall, the time he spent at the mall, and the time he spent walking from the mall to his mother's office.

First, let's add up the time it took for him to walk from his home to the mall (30 minutes), the time he spent at the mall (45 minutes), and the time it took to walk from the mall to his mother's office (15 minutes):
30 minutes + 45 minutes + 15 minutes = 90 minutes

Next, we'll convert the 90 minutes into hours. Since there are 60 minutes in an hour, we divide 90 by 60:
90 minutes รท 60 = 1.5 hours

Now, we'll subtract the 1.5 hours from the time Will arrived at his mother's office at 3 P.M.:
3 P.M. - 1.5 hours = 1:30 P.M.

So, Will left home at 1:30 P.M.
