Chapter 2: Q. 53 (page 67)

For exercises $53 - 55,$ use the following information.
Suppose the temperature $T^{o} (C)$ below Earth鈥檚 surface is given by $T (d) = 35 d + 20$ ,where $d$ is the depth $(km) .$
Find the temperature at a depth of $2$ kilometres.

Short Answer

Expert verified

The temperature at a depth of 2 kilometres is $90^{o} C$ .

Step by step solution

Step 1. Given information

A linear equation $T (d) = 35 d + 20$ and depth $(d) = 2 (k m) .$

Step 2. To find the temperature at depth of 2 (km)

Substitute the value of $d = 2$ in the given equation.

Now,

$\begin{array}{l} T (2) = 35 脳 2 + 20 \\ 鈬� T (2) = 70 + 20 \\ 鈬� T (2) = 90 \end{array}$

Step 3. Conclusion

Therefore, the value of $T (d)$ is $90$ at the depth is 2 kilometers. $(2, 70)$

Hence, the temperature at a depth of 2 kilometres is $90^{o} C$ .
