To find out how long Keiko played with her dog, we can subtract the start time from the end time.

Start time: 7:45 a.m.
End time: 8:18 a.m.

To calculate the duration:

  1. From 7:45 to 8:00 is 15 minutes.
  2. From 8:00 to 8:18 is an additional 18 minutes.

Now, we add those two intervals together:

15 minutes + 18 minutes = 33 minutes.

Therefore, Keiko played with her dog for 33 minutes.
