three and a half to four minutes
Three and half miles per 23 minutes. ;)
210 minutes
Half is 30.
There are 60 minutes in one hour. Therefore, to find the number of minutes in three and a half hours, you would multiply 60 by 3 to get 180 minutes for three hours, and then add half of 60 (30 minutes) to get a total of 210 minutes in three and a half hours.
3.5 hours is 210 minutes.
3.5 hours is 210 minutes.
From hours to minutes it is: 3.5*60 = 210 minutes
3.5
The entire speech, from start to finish, is about 8 and a half minutes long, very short.
Three hours is 180 minutes. 90 minutes is a half of this.
