John o kgweetsa ko ntlong ya tsala ya gagwe e e bokgakala jwa dimaele di le 200.  O kgweetsa ka lobelo lwa dimaele di le 70 ka ura.  O ne a tshwanetse go tsaya tsela e e mo kgutlisang morago e e oketsang leeto la gagwe ka dimaele di le 10. Fa a goroga koo o tsaya tsela e e boelelang gae e e bokgakala jwa dimaele di le 240 mme o kgweetsa dimaele di le 80 ka ura.  Leeto lotlhe le tsere lebaka le le kana kang?

A train travels between 3 different cities.  It goes 75 miles from the first city to the second city, 100 miles from the second city to the third city, and 50 miles less than that combined distance to go from the third city to the first city.  It does this trip 3 times a day.  The train needs service every 18,000 miles so how many days does it go between services?
Leeto la ntlha e ne e le dimaele di le 200+10=<<200+10=210>>210
Ka jalo o kgweetsa diura di le 210/70=<<210/70=3>>3
Tsela ya bobedi e tsere diura di le 240/80=<<240/80=3>>3
Ka jalo ka kakaretso o kgweetsa diura di le 3+3=<<3+3=6>>6

It takes 100+75=<<100+75=175>>175 miles for the first two legs of the trip
The third leg is 175-50=<<175-50=125>>125 miles
So the total trip is 175+125=<<175+125=300>>300 miles
So it goes 3*300=<<3*300=900>>900 miles per day
So it can go 18000/900=<<18000/900=20>>20 days between services.
