270
270 minutes.
1 hour = 60 minutes → 4½ hours = 4.5 × 60 minutes = 270 minutes
A bacteria splits in half after 20 minutes, so that after 20 minutes there are 2 bacteria, and after 40 minutes there are 4 bacteria. How many bacteria will there be after 2 hours?
1 day=24 hours 1 hour=60 minutes 1 minutes=60 seconds 4 hours 30 minutes=___________minutes =( 4x60 )minutes+30 minutes =240 minutes+30 minutes =270 minutes
Well, honey, if you can't do simple math, we've got a problem. There are 60 minutes in an hour, so in 4 and a half hours, you've got 4 hours x 60 minutes plus half an hour x 60 minutes. That's a grand total of 270 minutes. Math lesson over, class dismissed.
4 hours and 25 minutes.4 hours and 25 minutes.4 hours and 25 minutes.4 hours and 25 minutes.4 hours and 25 minutes.4 hours and 25 minutes.4 hours and 25 minutes.4 hours and 25 minutes.4 hours and 25 minutes.4 hours and 25 minutes.4 hours and 25 minutes.
41/2 hours is 270 minutes @60 minutes per hour.
There are exactly 4.5 minutes in 4 and a half minutes? Fascinating huh?
Note that you wrote 4.50 without any units. To be the same it would have to be - 4.50 hours or 4.5 hours.If written as 4:50 it is 4 hours 50 minutes. To have 4 1/2 hours it would be 4 hours & 30 minutes, or 4:30 (because 30 minutes is half of 60 minutes [which is 1 hour])
4 hours = 240 minutes 3 hours= 180 minutes
There are 240 minutes in 4 hours.60 Minutes = 1 Hour240 Minutes = 4 Hours
4.75 hours or 4 hours, 45 minutes
