Fishio o tsentse setshwantsho sa gagwe mo Instagram.  O bone dikeletso di le 2000 mo setshopong morago ga beke e le nngwe.  Morago ga dibeke di le tharo, palo ya dikeletso e ne e le palo ya ntlha ya dikeletso gompieno ga 70.  Fa a bone dikeletso tse dingwe tse disha di le 20000 bosheng, ke dikeletso di le kae tsa Instagram tse di leng teng?

Bill is trying to dig a well in his backyard. He can dig 4 feet/hour through soil and half that fast through clay. If he has to dig through 24 feet of soil and 8 feet of clay, how long will it take him to dig the well?
Morago ga go bona dikeletso di le 2000 mo setshopong sa gagwe mo Instagram mo bekeng ya ntlha, Fishio o bone dikeletso tse dingwe tse disha di le 70*2000 = <<70*2000=140000>>140000 mo setshopong morago ga dibeke tse dingwe di le tharo.
Palo yotlhe ya dikeletso mo dibekeng tse nne ke 140000+2000 = <<140000+2000=142000>>142000
Fa Fishio a bone dikeletso tse dingwe di le 20000 bosheng, palo ya dikeletso tse di mo setshopong ke 142000+20000=<<142000+20000=162000>>162000

First find how fast Bill can dig through clay: 4 feet/hour / 2 = <<4/2=2>>2 feet/hour
Then find how long he spends digging through clay in total: 8 feet / 2 feet/hour = <<8/2=4>>4 hours
Then find how long he spends digging through soil in total: 24 feet / 4 feet/hour = <<24/4=6>>6 hours
Then add the time he spends digging through soil and clay to find the total digging time: 4 hours + 6 hours = <<4+6=10>>10 hours
