Question

Dalam olimpiade sains, Ani melakukan percobaan di laboratorium. Sebongkah batu yang bersuhu - 12°C dipanaskan,rata rata kenaikan suhu 3°C setiap 4 menit. Jika batu tersebut dipanaskan selama 24 menit,berapa suhu akhir yang dicapai batu?​

Answer 1

6°C

Explanation:

English version

In the science olympiad, Ani conducted experiments in the laboratory. A rock with a temperature of -12 ° C is heated, the average temperature rise is 3 ° C every 4 minutes. If the stone is heated for 24 minutes, what is the final temperature achieved by the stone?

Solution

The initial temperature of the rock is -12 ° C.

The average temperature rise is 3 ° C every 4 minutes.

Since 24=6×4

So in 24 minutes, the temperature is going to rise by 18°C( 6×3=18)

Therefore the final temperature will be:

- 12°C+18°C=6°C

Therefore the final temperature is 6°C.
