...Hey guys. I need help with this question. I solved b) c) and d) through simple problem-solving, but im not sure how to do a)
The temperature of the Earth's crust is a linear function of the depth below the surface. An equation expressing the relationship is T = 0.01d + 20, with the temperature (T) in Celsius and the depth (d) in metres.
a) If you were to go down the shaft of an elevator in a mine at a rate of 5 m/s, express the temperature as a function of the time travelled in the elevator in seconds.
d = 5t
T = 0.01(5t) + 20
