30 minutes equal half an hour.
There are 5,400 seconds in an hour and a half.
There are 60 minutes in an hour therefore the number of minutes in half an hour is 60x0.5=30.
30 minutes = half an hour, because 60 minutes are one hour.
There are 30 minutes in half an hour and 15 minutes in a quarter of an hour
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.
150 (half, the other half are odd numbers)
