To find out how long Sophie ate dinner, we can subtract the start time from the end time.
Start time: 5:50 PM
End time: 6:18 PM
First, let's break it down:
- From 5:50 PM to 6:00 PM is 10 minutes.
- From 6:00 PM to 6:18 PM is 18 minutes.
Now we can add those two intervals together:
10 minutes + 18 minutes = 28 minutes.
So, Sophie ate dinner for 28 minutes.
