### Instruction:
 Porche ana masaa 3 ya kumaliza kazi zake zote za shule. Kazi yake ya hesabu inamchukua dakika 45. Kazi yake ya Kiingereza inamchukua dakika 30. Kazi yake ya sayansi inamchukua dakika 50. Kazi yake ya historia inamchukua dakika 25. Pia ana mradi maalum unaotakiwa siku inayofuata. Ana muda gani uliobaki kumaliza mradi huo?


### Response:
 Ana masaa 3 au dakika 180 za kufanya kazi.
Ameshatumia dakika 45 + dakika 30 + dakika 50 + dakika 25 = <<45+30+50+25=150>>150 kwenye kazi za shule.
Ana dakika 180 - dakika 150 zilizotumika kwenye kazi za shule = <<180-150=30>>30 za kumaliza mradi wake.
