from 2 and half minutes to 3 minutes.
150 minutes.
150 minutes = 2 and a half hours.
1,314,871.915 minutes.
150 minutes. One hour consists of 60 minutes. Two hours equals 120 minutes. Half of an hour would be 30 minutes. Which brings the total number of minutes in 2 and a half hours to 150.
150 minutes
2 or 4.5 min.
60 minutes in an hour; 30 minutes in a half hour. 5 and 1/2 = 330 minutes
1 hour, 2 minutes and 30 seconds.
There are 150 minutes in 2+1/2 hours; there are 60 minutes per hour.
60 minutes in an hour divided by 2( in other words cut in half) is 30, half an hour.
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?
