I need help with this question
Please give me the steps along with the answer

Answer:
2.55 is the answer!
Step-by-step explanation:
Depth = 1200 metres --> x = 1200 --> T = 4500 / 1200 = 3.75°C
Depth = 3750 metres --> x = 3750 --> T = 4500 / 3750 = 1.2 °C
The difference of the temperatures is 3.75°C - 1.2°C = 2.55°C
hope it helps!
