Matsaloli 3 da mafita game da daidaiton Sauri
1. Mota tana tafiya zuwa kudu na tsawon mita 100 cikin minti 1 sannan ta juya zuwa gabas mita 120 cikin minti 0.5. Ka tantance matsakaicin gudun motar.
Wanda aka sani:
Jimlar nisa = mita 100 + mita 120 = mita 220
Jimlar lokaci = minti 1 + minti 0.5 = minti 1.5 = daƙiƙa 90
Ana so: Matsakaicin gudu
Magani:
Tsarin gudu
Matsakaicin gudu = jimlar nisa: jimlar lokaci = mita 220: daƙiƙa 90 = mita 2.4/daƙiƙa
2. Jirgin ruwa yana tafiya a layi madaidaiciya na tsawon mita 100 bayan daƙiƙa 10. Menene matsakaicin gudun jirgin?
Wanda aka sani:
Nisa = mita 100
Lokaci = daƙiƙa 10
Ana so : Matsakaicin gudu
Magani:
Tsarin gudu
Matsakaicin gudu = mita 100: daƙiƙa 10 = mita 10/daƙiƙa
3. Ƙwayar cuta tana motsawa daga wuri O zuwa wuri B cikin daƙiƙa 4 kuma daga B zuwa A cikin daƙiƙa 20. Kayyade matsakaicin saurin ƙwayoyin.
An sani:
Nisa daga OB = mita 5
Nisa daga BA = mita 8
Lokacin OB = daƙiƙa 4
Lokacin BA = daƙiƙa 20
Ana so: Matsakaicin saurin ƙwayoyin cuta
Magani:
Tsarin gudu
Matsakaicin saurin ƙwayoyin = jimlar nisa: jimlar lokaci = (5 + 8): (4 + 20) = 13: 24 = mita 0.54/daƙiƙa
