The answer is 60+60+60+30=210 Minutes
Ninety minutes are in an hour and a half
There are 30 minutes in half an hour and 15 minutes in a quarter of an hour
30 minutes = half an hour, because 60 minutes are one hour.
30 minutes equal half an hour.
30 minutes are in half an hour.
There are 60 minutes in an hour therefore the number of minutes in half an hour is 60x0.5=30.
30 minutes.
30 minutes.
60 minutes. take one now, another in a half hour and another a half hour after that. a total of 60 minutes has transpired since you got the pills. it's supposed to be 90 minutes... why an hour?
One hour is 60 minutes so one and a half hour is 60 + 30=90 minutes
1 hour = 60 minutes, 1/2 hour = 30 minutes! Therefore 1 and a half hour would equal 90 minutes! Can't you add?
90 minutes.
