Kokelo e na le malao a le 1000 mme a le 1/5 a a dirisiwa. Ka ntlha ya leroborobo la coronavirus, balwetsi ba le 50 ba amogelwa kwa kokelong letsatsi le letsatsi. Bala palo yotlhe ya malao a a sa dirisiweng kwa kokelong morago ga dibeke di le 2.

How many minutes did she sleep on her bed that day?
Fa e le gore malao a le 1/5 a a dirisiwa mo kokelong, go raya gore malao a le 1/5 * 1000 = <<1000*1/5=200>>200 a a dirisiwa ke balwetsi.
Palo yotlhe ya malao a a sa dirisiweng kwa kokelong pele ga balwetsi ba basha ke malao a le 1000 - malao a le 200 = <<1000-200=800>>800.
Fa batho ba le 50 ba amogelwa letsatsi le letsatsi, palo yotlhe ya balwetsi mo kokelong morago ga beke ke balwetsi ba le 50 ka letsatsi * malatsi a le 7 ka beke = balwetsi ba le 350.
Morago ga dibeke di le pedi, palo yotlhe ya balwetsi ba ba amogetsweng kwa kokelong ke balwetsi ba le 350 ka beke * dibeke di le 2 = <<350*2=700>>700, yo mongwe le mongwe a dirisang bolao bo le bongwe.
Fa go ne go na le malao a le 800 a a sa dirisiweng kwa kokelong pele ga balwetsi ba basha, palo yotlhe e fokotsega go nna malao a le 800 - malao a le 700 = <<800-700=100>>100 a a sa dirisiweng.
