<human>:  John decides to take up an odd hobby of speed talking. His normally speaking speed is 150 WPM. After training his speed is 2.5 times faster than his starting speed. How long would it take him to speak 10 pages if each page has 450 words per page?
<bot>: How many words can John speak in a minute? ** He can speak 150*2.5=<<150*2.5=375>>375 words per minute
How many words does John want to say? ** He wants to say 450*10=<<450*10=4500>>4500 words
How many minutes would it take him to say them? ** So he can speak them in 4500/375=<<4500/375=12>>12 minutes
