Answer:
Difference = 2.25°
Explanation:
Here we are given that at depth the Temperature T is inversely proportional to the depth x.
∝


Where 4500 is constant
Now we have to find the difference in the temperature at 1200 mts and 3750 mts
1. x=1200



2. x=3750



Hence Difference is
T = 3.75 -1.20
= 2.25
Therefore The difference of the temperature at 1200 mts and 3750 mts is T=2.25°
