Question

The temperature within the Earth crust by about 30 degree Celsius for each kilomiter of depth below the surface. If the temperature at the earth surface is 24 degree Celsius at what depth would you expect the temperature to be 114 degree Celsius

Answer 1

Answer:

4 Km

Step-by-step explanation:

d = 30°

a= 24°

$a_{n}$ = 114°

∵ $a_{n}$ = a + (n-1)d

⇒ 114 = 24 + (n-1)30

  90 = (n-1)30

∴ n-1 =3

→ n = 4

At 4 Km depth temperature will be 114°C
