1 hour = 60 minutes.
One hour is 60 minutes so one and a half hour is 60 + 30=90 minutes
If the question is, How many minutes is one tenth of an hour ? Then,1 hour = 60 minutes1/10 hour = 60/10 = 6 minutes.
There are 20 minutes in one third of an hour.
One third of an hour is 20 minutes.
There are 15 minutes in a quarter hour.
30 minutes = half an hour, because 60 minutes are one hour.
There are 80 minutes in 1 hour and 20 minutes.
There are 60 minutes in one hour, therefore, one sixth of an hour is equal to 60 / 6 = 10 minutes.
There are 30 minutes in half an hour and 15 minutes in a quarter of an hour
100 minutes
that is easy so if 60 seconds are in one hour and 60 minutes in a hour there is about 70 seconds in a hour and 10 minutes
There are 60 minutes in one hour. Therefore, one eighth of an hour is equal to 60/8 = 7.5 minutes, or 7 minutes 30 seconds.
