Hii hapa suluhisho:

Kupunguza muda:

Badilisha dakika kuwa sekunde
- 11 dakika = 11 × 60 sekunde = 660 sekunde
- 8 dakika = 8 × 60 sekunde = 480 sekunde
Ongeza sekunde zilizobaki
- 11 min 40 sec = 660 sekunde + 40 sekunde = 700 sekunde
- 8 min 25 sec = 480 sekunde + 25 sekunde = 505 sekunde
Punguza muda wa pili kutoka wa kwanza
- 700 sekunde - 505 sekunde = 195 sekunde
Badilisha sekunde kurudi dakika na sekunde
- 195 sekunde ÷ 60 sekunde/dakika = 3 na baki 15
- Hii inamaanisha dakika 3 na sekunde 15.
Jibu ni 3 dakika na 15 sekunde.
