Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! derek types 4800 words in 2 hours and 30 minutes.
30 minutes = .5 hours
derek types 4800 words in 2.5 hours
divide 4800 by 2.5 and you get:
derek types 4800/2.5 = 1920 words in 1 hour.
there are 60 minutes in an hour.
divide 1920 by 60 and you get:
derek types 1920 / 60 = 32 words per minute.
there are 150 minutes in 2 hours and 30 minutes.
32 * 150 = 4800
everything checks out so the answer is good.
the answer is:
derek types approximately 32 words per minute.
since they didn't specify hours or minutes, you could also have said that derek types 1920 words per hour, but per minute is the normal standard for typing speed, so i would go with the per minute figure.
