Hours to minutes
2 hours is the same as 120 minutes.
Multiply the number of hours by 60.
Year 4
Solve problems involving converting from hours to minutes; minutes to seconds; years to months; weeks to days
Use known time relationships to convert between units and solve practical time problems.
Lesson overview
Time
Time units are linked. There are 60 minutes in an hour, 60 seconds in a minute, 12 months in a year and 7 days in a week. Knowing these facts helps solve time problems efficiently.
Minutes to seconds
3 minutes is the same as 180 seconds.
Each minute has 60 seconds.
Years and weeks
1 year has 12 months and 3 weeks have 21 days.
Use the known time relationships first.
Worked example
How many days are in 5 weeks?
- 1 week has 7 days.
- 5 weeks are 5 groups of 7 days.
- 5 x 7 = 35.
- So 5 weeks is 35 days.
Round 1: Learn it
