3 ngā raruraru me ngā otinga mō te whārite Tere
1. Ka haere tētahi motuka ki te tonga mō te 100 m i roto i te 1 meneti, kātahi ka huri ki te rawhiti mō te 120 m i roto i te 0.5 meneti. Tātaihia te tere toharite o te motuka.
Mōhiotia:
Tapeke tawhiti = 100 mita + 120 mita = 220 mita
Te wā katoa = 1 meneti + 0.5 meneti = 1.5 meneti = 90 hēkona
E hiahiatia ana: Te tere toharite
Rongoā:
Tātai tere
Tere toharite = tawhiti katoa: wā katoa = 220 mita: 90 hēkona = 2.4 mita/hēkona
2. He poti e haere tika ana mō te tawhiti o te 100 mita i muri i te 10 hēkona. He aha te tere toharite o te poti?
Mōhiotia:
Tawhiti = 100 mita
Wā = 10 hēkona
E hiahiatia ana : Te tere toharite
Rongoā:
Tātai tere
Tere toharite = 100 mita : 10 hēkona = 10 mita/hēkona
3. Ka neke tētahi matūriki mai i te pūwāhi O ki te pūwāhi B i roto i te 4 hēkona, ā, mai i B ki A i roto i te 20 hēkona. Tātaihia te tere toharite o ngā matūriki.
Kua mohiotia:
Te tawhiti o OB = 5 mita
Te tawhiti o BA = 8 mita
Te wā o OB = 4 hēkona
Wā BA = 20 hēkona
E hiahiatia ana: Te tere toharite o ngā matūriki
Rongoā:
Tātai tere
Ko te tere toharite o ngā matūriki = te tawhiti katoa: te wā katoa = (5 + 8) : (4 + 20) = 13 : 24 = 0.54 mita/hēkona
