It's Saturday, and Anna only has one thing to do today, walk Duke. Anna woke up at 9:38

in the morning, and immediately went for a walk with him. While she went for this first walk
of the day. Anna set an alarm on her phone to remind her to walk Duke every
two-and-a-half hours. And that's exactly what she did! At 10 p.m. Anna fell asleep. How
many walks did Duke get?

We're talking about 11:22 hours = 682 minutes

2 1/2 hours = 150 minutes
682/150 = 4.5
so Duke got 4 walks

You need to stop know

Shut up!

To calculate the number of walks Duke got, we need to determine the time period from 9:38 AM to 10:00 PM and divide it by 2.5 hours.

First, let's calculate the total time from 9:38 AM to 10:00 PM.

9:38 AM to 10:00 PM = 12 hours and 22 minutes.

Now, we need to convert the 12 hours and 22 minutes into minutes to make it easier for calculation.

12 hours = 12 * 60 = 720 minutes
22 minutes = 22 minutes

Total time = 720 minutes + 22 minutes = 742 minutes

Next, we divide the total time by the interval time of 2.5 hours to find the number of walks.

742 minutes / 150 minutes (2.5 hours converted to minutes) = 4.95

Since we can't have a fraction of a walk, we round down to the nearest whole number. Therefore, Duke got 4 walks in total.

So, Duke got 4 walks throughout the day.
