Mathata a 3 le litharollo mabapi le equation ea Speed
1. Koloi e tsamaea ho ea boroa ka limithara tse 100 ka motsotso o le mong ebe e retelehela bochabela ka limithara tse 120 ka metsotso e 0.5. Fumana lebelo le tloaelehileng la koloi.
Tse tsejoang:
Kakaretso ea sebaka = limithara tse 100 + limithara tse 120 = limithara tse 220
Kakaretso ea nako = motsotso o le 1 + metsotso e 0.5 = metsotso e 1.5 = metsotsoana e 90
Ho batloa: Lebelo le tloaelehileng
tharollo:
Foromo ea lebelo
Lebelo le tloaelehileng = sebaka sohle: nako yohle = limithara tse 220: metsotsoana e 90 = limithara tse 2.4/motsotsoana
2. Sekepe se tsamayang moleng o otlolohileng sebaka sa limithara tse 100 kamora metsotsoana e 10. Lebelo le tloaelehileng la sekepe ke lefe?
Tse tsejoang:
Sebaka = limithara tse 100
Nako = metsotsoana e 10
Ho batloa : Lebelo le tloaelehileng
tharollo:
Foromo ea lebelo
Lebelo le tloaelehileng = limithara tse 100: metsotsoana e 10 = limithara tse 10 ka motsotsoana
3. Phatsa e tloha ntlheng ea O ho ea ntlheng ea B ka metsotsoana e 4 le ho tloha ho B ho ea ho A ka metsotsoana e 20. Fumana lebelo le tloaelehileng la likaroloana.
Tsejoa:
Sebaka sa OB = limithara tse 5
Sebaka sa BA = limithara tse 8
Nako ea OB = metsotsoana e 4
Nako ea BA = metsotsoana e 20
Ho batloa: Lebelo le tloaelehileng la likaroloana
tharollo:
Foromo ea lebelo
Lebelo le tloaelehileng la likaroloana = sebaka se felletseng : nako eohle = (5 + 8): (4 + 20) = 13 : 24 = 0.54 metres/motsotsoana
