Question

I dont understand this can someone please help me.​

Answer 1

Difference = 2.25°

Explanation:

Here we are given that at depth the Temperature T is inversely proportional to the depth x.

`T` ∝
`(1)/(x)`

`T= 4500 * (1)/(x)`

Where 4500 is constant

Now we have to find the difference in the temperature at 1200 mts and 3750 mts

1. x=1200

`T= 4500 * (1)/(x)`

`T= 4500 * (1)/(1200)`

`T= 3.75`

2. x=3750

`T= 4500 * (1)/(x)`

`T= 4500 * (1)/(3750)`

`T=1.2`

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°
