Janet o kokoanya maduo a tlhatlhobo ya sekolo ya ngwaga le ngwaga ya sekolo se sebotlana sa Herbert Hoover.  Baithuti ba le 340 go tswa go ba le 500 ba mophato wa boraro ba se na go fetela kwa mophatong o o latelang, gammogo le baithuti ba le 40 go tswa go ba le 100 ba mophato wa bone.  Baithuti ba mophato wa botlhano ba le 400 ba ne ba na le palo ya ba ba fetileng e e fetang ya ba mophato wa bone gabedi.  Palo ya ba ba fetileng mo sekolong yotlhe ke bokae?

Two cars are driving on a highway.  The first car is traveling at an average speed of 60 miles per hour when the second car passes it at an average speed of 70 miles per hour.  If both cars continue on the highway at the same speed, how many miles will separate them after 2 hours?
Sa ntlha, bona palo ya ba ba fetileng mo baithuting ba mophato wa bone: baithuti ba le 40 / baithuti ba le 100 = <<40/100=.4>>.4
Morago ga foo, oketsa palo eo gabedi go bona palo ya ba ba fetileng mo baithuting ba mophato wa botlhano: .4 * 2 = <<.4*2=.8>>.8
Morago ga foo, atisa palo ya ba ba fetileng mo baithuting ba mophato wa botlhano ka palo ya baithuti ba mophato wa botlhano go bona palo yotlhe ya baithuti ba mophato wa botlhano ba ba fetileng: .8 * baithuti ba mophato wa botlhano ba le 400 = <<.8*400=320>>baithuti ba mophato wa botlhano ba le 320
Jaanong, tlhakanya palo ya baithuti ba ba fetileng go tswa mo mophatong mongwe le mongwe go bona palo yotlhe ya baithuti ba ba fetileng: baithuti ba le 320 + baithuti ba le 40 + baithuti ba le 340 = <<320+40+340=700>>baithuti ba le 700
Tlhakanya palo yotlhe ya baithuti ba mophato mongwe le mongwe go bona palo yotlhe ya baithuti: baithuti ba le 400 + baithuti ba le 100 + baithuti ba le 500 = <<400+100+500=1000>>baithuti ba le 1000
Sa bofelo, arola palo ya baithuti ba ba fetileng ka palo yotlhe ya baithuti mme o atise ka 100% go bona palo yotlhe ya ba ba fetileng: baithuti ba le 700 / baithuti ba le 1000 * 100% = 70%

In two hours, the first car will have traveled 60*2 = <<60*2=120>>120 miles.
Similarly, the second car will have traveled 70*2 = <<70*2=140>>140 miles.
Thus, the cars are separated by 140 - 120 = <<140-120=20>>20 miles after two hours.
