Sally o ile kwa lewatleng ka malatsi a boikhutso. Batsadi ba gagwe ba mo neetse R10 go reka sengwe le sengwe se a se batlang. Kwa lebenkeleng la dikgabisanyo, ditlhare tsa taffy di ne di rekisiwa ka theko e e reng "Reka pontsho e le nngwe ka R3, o bone pontsho e nngwe halofo theko." O ne a ithekela diponto di le pedi. Gape o rekile mokotla o o tlhakanetsweng wa dikgapetla tsa lewatle ka R1.50 le dimagnet di le 4 tse di jang R0.25 nngwe le nngwe. Go setse bokae mo go Sally?

Toby is reading a book that is 45 pages long. It averages 200 words a page. Toby can read at a rate of 300 words per minute. He has to be at the airport in 60 minutes and plans to leave as soon as he finishes the book. It takes 10 minutes to get to the airport. How many minutes early will Toby be?
Taffy e reka pontsho e le nngwe ka R3 mme e bona pontsho e nngwe halofo theko. Ka jalo halofo theko ya pontsho e le nngwe ke R3/2 = R1.50+R3.00=R4.50
Dimagnet di le 4 ka R0.25 nngwe le nngwe ke 4*0.25=R<<4*0.25=1.00>>1.00
Fa o tlhakanya tsotlhe tse a di rekileng, R4.50+R1.50+R1.00 = R<<4.5+1.5+1=7.00>>7.00
O ne a na le R10 mme a dirisa R7 ka jalo o setse ka R10-R7 = R<<10-7=3.00>>3.00

He can read 1.5 pages in a minute because 300 / 200 = <<300/200=1.5>>1.5
It will take 30 minutes to read the book because 45 / 1.5 = <<45/1.5=30>>30
He will arrive at the airport 40 minutes from now because 30 + 10 = <<30+10=40>>40
He will be 20 minutes early because 60 - 40 = <<60-40=20>>20
