Garrett o a budulela dijwana tsa mmidi go itirela dijo tsa go tlhapa. Fa pane e ntse e gotela, dijwana tsa mmidi di simolola go thunya ka lobelo. Tse 20 di a thunya mo metsotswaneng ya ntlha e le 30 ya go besa, morago ga moo go thunya palo e e fetang ya ntlha gararo mo metsotswaneng e mengwe e le 30. Palo ya dijwana tsa mmidi tse di thunyang e oketsega go nna palo e e fetang ya ntlha gane mo metsotswaneng e mengwe e le 30, mme mo metsotswaneng ya bofelo e le 30, go thunya ga dijwana go fokotsega go nna sepofotlo sa palo ya metsotswana e e fetileng e le 30. Morago ga gore Garrett a tlose pane mo molelong, kwatara ya palo ya dijwana tsa mmidi tse di thuntseng mo metsotswaneng ya bofelo e le 30 ya go besa le yona e a thunya ka ntlha ya mogote o o setseng.

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?
Mo metsotswaneng ya bobedi e le 30 ya go besa, go thunya dijwana di le 3 * 20 = <<3*20=60>>60.
Mo metsotswaneng ya boraro e le 30, go thunya dijwana di le 4 * 20 = <<4*20=80>>80.
Mo metsotswaneng ya bofelo e le 30, go thunya dijwana di le 80 / 2 = <<80/2=40>>40.
Morago ga go besa, mogote o o setseng o dira gore go thunya dijwana di le 40 / 4 = <<40/4=10>>10.
Ka jalo, Garrett o na le dijwana tsa mmidi di le 20 + 60 + 80 + 40 + 10 = <<20+60+80+40+10=210>>210.

He can speak 150*2.5=<<150*2.5=375>>375 words per minute
He wants to say 450*10=<<450*10=4500>>4500 words
So he can speak them in 4500/375=<<4500/375=12>>12 minutes
