Imibuzo yokuqala engu-10 yesigaba ngasinye mahhala.

Qala ngokuguqula amayunithi: imizuzu ibe amahora, amamitha abe amakhilomitha.
Ukuya komunye nomunye: hlanganisa amajubane. Uhlangothi olufanayo: susa elinye kwelinye.
Ijubane elimaphakathi liyibanga lilonke ÷ isikhathi sisonke, hhayi isilinganiso samajubane.

Imibuzo emithathu exazululiwe yalolu hlobo. Zama ngamunye kuqala, bese ufunda impendulo nendlela yokuyithola.

Isibonelo 1

Imoto ihamba ibanga elingu-320 km emahoreni angu-8. Siyini isivinini sayo esimaphakathi ngo-km/h?

Impendulo elungile: B

Indlela yokuxazulula

Isivinini = ibanga ÷ isikhathi = 320 ÷ 8 = 40 km/h.

Isibonelo 2

Imoto ihamba ngesivinini esingu-75 km/h amahora angu-6. Ihamba ibanga elingakanani?

Impendulo elungile: B

Indlela yokuxazulula

Ibanga = isivinini × isikhathi = 75 × 6 = 450 km.

Isibonelo 3

Imoto ihamba ngesivinini esingu-40 km/h amahora angu-3. Ihamba ibanga elingakanani?

Impendulo elungile: D

Indlela yokuxazulula

Ibanga = isivinini × isikhathi = 40 × 3 = 120 km.
