4 Izibonelo zemibuzo yebanga kanye nokufuduka
1. Imoto iqonde empumalanga amamitha ayi-100 bese iqonda entshonalanga amamitha angama-50. Thola ibanga kanye nokufuduka kwemoto kusukela endaweni yayo yokuqala.
Ingxoxo
Ibanga = amamitha ayi-100 + amamitha angama-50 = amamitha ayi-150
Inani lokufuduka = amamitha ayi-100 – amamitha angama-50 = amamitha angama-50 futhi indlela yokufuduka ibheke empumalanga.
2. Umfundi uhamba amamitha angu-4 empumalanga bese ejika enyakatho amamitha angu-3. Thola ibanga kanye nokufuduka komfundi kusukela endaweni yokuqala.
Ingxoxo
Ibanga = amamitha ayi-4 + amamitha angama-3 = amamitha ayi-7
Ukufuduka okukhulu = ubude be-hypotenuse = = amamitha.
Isiqondiso sokunyakaza sisenyakatho-mpumalanga (isiqondiso somcibisholo ophuzi).
3. Bheka isithombe esingezansi! Umuntu uzungeza insimu engunxande. Ubude = amamitha angu-50, ububanzi = amamitha angu-20. Ngemva kokuzungeza insimu kabili, umuntu ubuyela endaweni yakhe yokuqala. Thola ibanga kanye nokufuduka komuntu.
Ingxoxo
Umngcele wensimu = 2 (amamitha angu-50) + 2 (amamitha angu-20) = amamitha ayi-100 + amamitha angu-40 = amamitha angu-140.
Insimu izungezwe izikhathi ezimbili = 2 (amamitha angu-140) = amamitha angu-280.
Ibanga = amamitha angu-280.
Ngemva kokujikeleza insimu, umuntu wabuyela endaweni yakhe yokuqala ngenxa yalokho. ukufuduka = amamitha angu-0.
4. Umuntu usezophuma ekhaya ngesithuthuthu. Lapho ehamba, i-speedometer ikhombisa amakhilomitha ayi-10.500. Ngemva kokubuyela ekhaya, i-speedometer yesithuthuthu ikhombisa amakhilomitha ayi-10.700. Thola ibanga kanye nokufuduka komuntu!
Ingxoxo
Umehluko ngezinombolo ku-speedometer = 10.700 km – 10.500 km = 200 km.
Ibanga = 200 km.
Ngemva kokuhamba, umuntu ubuyela ekhaya lakhe (isikhundla sakhe sokuqala) ukuze ukufuduka = 0 km.
Imibuzo mayelana nebanga kanye nokufuduka
1. Imoto iqonde empumalanga amamitha ayi-80 bese iqonda entshonalanga amamitha angama-60. Thola ibanga kanye nokufuduka kwemoto kusukela endaweni yayo yokuqala.
2. Umfundi uhamba amamitha angu-8 empumalanga bese ejika enyakatho amamitha angu-6. Thola ibanga kanye nokufuduka komfundi kusukela endaweni yokuqala.
3. Bheka isithombe esingezansi! Umuntu uzungeza insimu engunxande. Ubude = amamitha ayi-100, ububanzi = amamitha angama-50. Ngemva kokuzungeza insimu kathathu, umuntu ubuyela endaweni yakhe yokuqala. Thola ibanga kanye nokufuduka komuntu.
4. Umuntu usezophuma ekhaya ngesithuthuthu. Lapho ehamba, i-speedometer ikhombisa amakhilomitha ayi-11.600. Ngemva kokubuyela ekhaya, i-speedometer yesithuthuthu ikhombisa amakhilomitha ayi-11.900. Thola ibanga kanye nokufuduka komuntu!
