Ukusetshenziswa kwesikhathi kungahlenwa ngale ndlela: ISIQEPHU A: Imizuzu engama-40 ISIQEPHU B: Imizuzu engama-55 ISIQEPHU C: Imizuzu engama-55 Bhala phezulu ngezikhathi ezisongekayo。 - NSC IsiZulu HL - Question 10 - 2021 - Paper 2

Ukubala isikhathi esiphelele esichithwe ezikhathini ezihlukene, kufanele sihlanganise imizuzu yeziqephu ezithile:

1. ISIQEPHU A: 40 imizuzu
2. ISIQEPHU B: 55 imizuzu
3. ISIQEPHU C: 55 imizuzu

Sizocacisa lezi zikhathi:

$ext{Isikhathi Esiphelele} = ext{ISIQEPHU A} + ext{ISIQEPHU B} + ext{ISIQEPHU C}$

Ngakho-ke:

$ext{Isikhathi Esiphelele} = 40 + 55 + 55$

$ext{Isikhathi Esiphelele} = 150 ext{ imizuzu}$

Lokhu kusho ukuthi isikhathi esiphelele sokwenza lezi ziqephu ezahlukene singu-150 imizuzu.
