Two half-hours.
There are 60 minutes in 1 hour so there are 60 x 5.5 minutes in five and a half hours, which is 330 minutes.
60
1 hour = 60 minutes → 4½ hours = 4.5 × 60 minutes = 270 minutes
60 seconds an 1 minute 60 minutes in 1 hour 30 minutes in half an hour 90 minutes in one and a half hours. So 90 minutes * 60 seconds = 5400 seconds
60 minutes = 1 hour 112.5 minutes = x hours x=112.5/60 x=1.875
There are 3.5 times 60 = 210 minutes
If that's hours then there are 3.5*60 = 210 minutes
An hour is equal to 60 minutes, so 150 minutes is equal to 2 and a half hours or 2 hours and 30 minutes.Two hours and thirty minutes, or two and a half hours, or 2.5 hours.
there are 60 minutes in an hour so there is 1 and a half hours in 90 minutes
1 day = 24 hours so 2.5 days = 2.5*24 = 60 hours 1 hour = 60 minutes so 60 hours = 60*60 = 3600 minutes.
There are 60 minutes in one hour. 0.5 hours is the same as half an hour, so half of sixty minutes is 30 minutes.
You have to know that there are 60 minutes in an hour. "2 and one half hours" = 2.5 hours (2.5 hours)*(60 minutes/hour) = 150 (hours*minutes/hour) = 150 minutes Note that you multiply & divide the units as if they were numbers. This is dimensional analysis.
