There are 150 minutes in 2+1/2 hours; there are 60 minutes per hour.
150 minutes in 2 1/2 hours (60 * 2.5 = 150)
210 minutes are in 3 and 1/2 hours. MARKED
An hour is equal to 60 minutes, so 150 minutes is equal to 2 and a half hours or 2 hours and 30 minutes.Two hours and thirty minutes, or two and a half hours, or 2.5 hours.

You have to know that there are 60 minutes in an hour. "2 and one half hours" = 2.5 hours (2.5 hours)*(60 minutes/hour) = 150 (hours*minutes/hour) = 150 minutes Note that you multiply & divide the units as if they were numbers. This is dimensional analysis.
Two and a half hours is equal to 150 minutes. To convert hours to minutes, you multiply the number of hours by 60 since there are 60 minutes in an hour. Therefore, 2.5 hours x 60 minutes/hour = 150 minutes.
It's 2 and a half hours, you've already answered it!
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?
