Question

At a depth of x metres, the temperature of the water in an ocean is T degrees Celsius. At depths below 900 metres, T is inversely proportional to x. T is given by T=4500/x. Work out the difference in the temperature of the water at a depth of 1200 metres and the temperature of the water at a depth of 3750

Answer 1

$\underline {\text {Given:} }$

$\text{Depth of the water = x m}$

$\text{Temperature of the water = T}^\circ c$

$\text{Equation : T} = \dfrac{4500}{x}$

$\underline {\text {To Find:} }$

$\text{The difference in temperature at depth 1200 m and 3750 m}$

$\boxed {\textbf{Solution}}$

$\underline {\text {Find thee temperature at the depth of 1200 m:} }$

$\text{T} = \dfrac{4500}{1200}$

$\text{T} =3.75^\circ$

$\underline {\text {Find thee temperature at the depth of 3750 m:} }$

$\text{T} = \dfrac{4500}{3750}$

$\text{T} =1.2^\circ$

$\underline {\text {Find thee difference in the temperature:} }$

$\text{T} = 3.75 - 1.2$

$\text{T} =2.55^\circ$

$\boxed {\boxed{ \textbf{Answer: 2.55}^\circ }}$
