3.5 hours.
150 minutes
There are 60 minutes in one hour. Therefore, 3 hours 30 minutes is equal to (3 x 60) + 30 = 210 minutes.
210 minutes is equal to 3.5 hours, or 3 hours and 30 minutes.
I assume 0.5 hours. 0.5 hours is 30 minutes
There are 60 minutes in one hour, so 120 minutes is equal to 2 hours and 150 minutes is equal to 2 hours and 30 minutes (or 2 and 1/2 hours).
330 minutes is 5 hours and 30 minutes.
150 minutes
210 = 60 + 60 + 60 + 30
There are 60 minutes in one hour. Therefore, 3 hours 30 minutes is equal to (3 x 60) + 30 = 210 minutes.
210 minutes is equal to 3.5 hours, or 3 hours and 30 minutes.
I assume 0.5 hours. 0.5 hours is 30 minutes
There are 60 minutes in one hour. Therefore, 30 hours is equal to 30 x 60 = 1800 minutes.
There are 60 minutes in one hour, so 120 minutes is equal to 2 hours and 150 minutes is equal to 2 hours and 30 minutes (or 2 and 1/2 hours).
There are 60 minutes in an hour. Therefore: 90 = 1.5 or 1 hours 30 minutes
There are 0.5 hours in 30 minutes. This is because one hour is equal to 60 minutes, so you can calculate it by dividing 30 by 60. Thus, 30 minutes is half of an hour.
(20 hours 30 minutes) - (5 hours 45 minutes) = 14 hours 45 minutes.
2.5 hours is exactly 2.5 hours!
