plis dijawab kak pake cara

[tex]12.00 - 07.00 = 5 \: jam \: \times 2 = 10 + 13 = 23[/tex]
[tex]22.00 - 12.00 = 10 \: jam \times 1.5 = 15[/tex]
[tex]23 - 15 = 8[/tex]
[tex]a. \: 8[/tex]
[tex]maaf \: kalau \: salah \: semoga \: bermanfaat \: [/tex]

07.00 = 13°C

setiap jam ber+ = 2°C

puncak ber+ nya suhu = 12.00

12.00 - 07.00 = 5jam x 2 = 10°C

13°C+10°C = 23°C

22.00 = turun 1,5°C perjam

22.00 - 12.00 = 10jam x 1,5 = 15°C

23°C - 15°C

= 8°C (A)

maaf klo slh
