Berapa jam yang akan ditempuh oleh sebuah kereta api dengan kecepatan 70kilometer per jam dan panjanh jaln 350
Answer (4)
ok what do we know.
when the kettle is full its 2900g when its half full is 2050g
that means that half the weight of water in the kettle was 850g so the other remaining half has to be 850g
850+850=1700
1700g is the weight of the **water **but we want to know the weight of the kettle when its empty so you had 2900g when the kettle was full lets say you poured all 1700g of the water out you would be left with... **
2900-1700= 1200g **this means the kettle when empty weighs 1200g **
**
The mass of the kettle when it is empty is 1200 grams. We calculated this by using the total mass of the kettle when full and half full, finding that the weight of just the water is 1700 grams. Subtracting this from the full mass gives the empty kettle's mass.
