Today, we are going to be learning to find the duration between two times. The clocks you made last week will come in useful today.
This website is great and it also has a duration function at the bottom right corner to help you. https://www.visnos.com/demos/clock
Duration is the length of time something happens for. The duration of the school day is 6 hours and 15 minutes. The duration of playtime is 15 minutes. The duration of Miss Millar’s coffee making is about 5 minutes.
Remember that there are 60 minutes in an hour. When counting duration from 12:30 to 14:10. There are 30 minutes to 13:00, another 60 minutes to 14:00 and then 10 minutes to 14:10. The duration is 30+60+10 = 100 minutes. (We can also say 1 hour and 40 minutes)
