1 hour = 60 minutes so 1.5 hours = 1.5*60 = 90 minutes. So simple!
90 = 60 + 30 = 60 x 1.5
90
One hour is 60 minutes so one and a half hour is 60 + 30=90 minutes
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
90 minutes
One and one half of an hour equal 90 minutes.
90 minutes
2.5 minutes
There are thirty minutes in one half hour.
One-hundred-and-fifty minutes is equivalent to two-and-a-half hours.
60 minutes equals an hour and half an hour is 30 minutes so 60 min+30 min =90 minutes.
one hour is sixty mins half an hour is 30 so: 2x60+30=150 minutes
One and a half hour is 90 minutes.
