Question

Please please help!!

Volcanoes prove that the Earth's center is hot. The formula T= 10d +20 is used to estimate the temperature, T degrees Celcius, at a depth of d kilometres (km).
A) what does each term on the right side of the equation represent?
B) Estimate the depth where the temperature is 60 degrees C.
C) What is the approximate temperture at a depth of 4km?

Answer 1

The formula T= 10d +20

A) what does each term on the right side of the equation represent?

• 10d⇒ 10 degrees increase per 1 km and 20 deg surface temperature

B) Estimate the depth where the temperature is 60 degrees C.

• 60=10d+20
• 10d=40
• d=4 km

C) What is the approximate temperature at a depth of 4km?

• T=10*4+20
• T=60 deg
