Learn about time, specifically converting between 12 and 24 hour times, converting between hours and minutes and problems requiring calculation with time. This course is ideal for beginners.
Introduction
We write the time in hours and minutes with either a
full stop or a colon in between.
For example, twenty past nine can be written in the following ways:
· 9:20 (using a colon – there is a colon between the 9 and the 20)
· 9.20 (using a full stop)
Time is a non-decimal system. This means it is not measured in tens. For example:
· One day is 24 hours
· One hour is 60 minutes
· One minute is 60 seconds
Because of this, you need to be careful when making calculations that involve hours and minutes.
