Mico le Marco ba batla go itsane. Ba lemogile gore bogolo jwa dingwaga tsa bone ka bobedi ke 20. Bogolo jwa dingwaga tsa bone bo tla bo bo kae mo dingwageng di le 10? 

It takes Matthew 3 minutes to dig a small hole for shrubs and 10 minutes to dig a large hole for trees.  How many hours will it take him to dig 30 small holes and 15 large holes?
Go tla nna le dingwaga di le 10 (tsa ga Mico) + 10 (tsa ga Marco) = <<10+10=20>>20 go tlaleletsa mo palong ya dingwaga tsa bone tsa gompieno morago ga dingwaga di le 10. 
Ka jalo, bogolo jwa dingwaga tsa bone mo dingwageng di le 10 e tla nna 20 + 20 = <<20+20=40>>40.

It takes 3 minutes to dig a small hole and he needs to dig 30 small holes so it will take 3*30 = <<3*30=90>>90 minutes
It takes 10 minutes to dig a large hole and he needs to dig 15 large holes so it will take him 15*10 = <<10*15=150>>150 minutes
It will take 90 minutes to dig the small holes and 150 minutes to dig the large holes for a total of 90+150 = <<90+150=240>>240 minutes
There are 60 minutes in 1 hour and he needs to dig for 240 minutes so that's 240/60 = <<240/60=4>>4 hours
