Whakaoti i te ?m/s=72km/h

$$? m / s = 72 km / h$$

Whakaoti mō h

$$\left\{\begin{matrix}h=72ks\text{, }&k\neq 0\text{ and }s\neq 0\\h\neq 0\text{, }&m=0\text{ and }s\neq 0\end{matrix}\right.$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe h ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te hs, arā, te tauraro pātahi he tino iti rawa te kitea o s,h.

$$hm=s\times 72km$$

Whakaraupapatia anō ngā kīanga tau.

$$hm=72kms$$

He hanga arowhānui tō te whārite.

$$mh=72kms$$

Whakawehea ngā taha e rua ki te m.

$$\frac{mh}{m}=\frac{72kms}{m}$$

Mā te whakawehe ki te m ka wetekia te whakareanga ki te m.

$$h=\frac{72kms}{m}$$

Whakawehe 72kms ki te m.

$$h=72ks$$

Tē taea kia ōrite te tāupe h ki 0.

$$h=72ks\text{, }h\neq 0$$

Whakaoti mō k

$$\left\{\begin{matrix}k=\frac{h}{72s}\text{, }&s\neq 0\text{ and }h\neq 0\\k\in \mathrm{R}\text{, }&m=0\text{ and }s\neq 0\text{ and }h\neq 0\end{matrix}\right.$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te hs, arā, te tauraro pātahi he tino iti rawa te kitea o s,h.

$$hm=s\times 72km$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$s\times 72km=hm$$

He hanga arowhānui tō te whārite.

$$72msk=hm$$

Whakawehea ngā taha e rua ki te 72sm.

$$\frac{72msk}{72ms}=\frac{hm}{72ms}$$

Mā te whakawehe ki te 72sm ka wetekia te whakareanga ki te 72sm.

$$k=\frac{hm}{72ms}$$

Whakawehe hm ki te 72sm.

$$k=\frac{h}{72s}$$
