Example 1:
Convert 300 minutes to hours.
There are 60 minutes in every hour.
To convert from minutes to hours we need to divide by 60.
300 ÷ 60
300 ÷ 60 is the same as 30 ÷ 6 (this is like simplifying a fraction)
30 ÷ 6 = 5
There are 5 hours in 300 minutes.
Example 2:
Convert 7 hours to minutes.
There are 60 minutes in every hour. To convert from hours to minutes we need to multiply by 60.
7 × 60
7 × 60 = 420
There are 420 minutes in 7 hours.
Example 3:
Convert 281 minutes to hours. Give your answer in hours and minutes.
There are 60 minutes in every hour. We can write down the 60 times table to see how many whole hours are in 281 minutes.
4 hours = 240 minutes
There are 4 whole hours in 281 minutes.
We can calculate how many additional minutes there are by taking 240 away from 281
281 - 240 = 41
281 minutes = 4 hours and 41 minutes.
Example 4:
A film starts at 7:50 pm and runs for 89 minutes. Work out the time when the film ends.
There are 60 minutes in every hour.
We need 10 minutes to get to the next hour (8 pm). 89 - 10 = 79 (there are 79 minutes of film left)
Another 60 minutes will get to 9 pm. 79 -60 = 19 (there are 19 minutes of the film left)
9pm + 19 minutes = 9.19 pm
