Table 1.18 gives the average temperature, T, at a depth d, in a borehole in Belleterre, Quebec.13 Evaluate ΔT/Δd on the the following intervals, and explain what your answers tell you about borehole temperature.
(a) 25 ≤ d ≤ 150
(b) 25 ≤ d ≤ 75
(c) 100 ≤ d ≤ 200

a.) For 25 ≤ d ≤ 150;
ΔT/Δd = (5.50 - 5.50)/(150 - 25) = 0/125 = 0

b.) For 25 ≤ d ≤ 75;
ΔT/Δd = (5.10 - 5.50)/(75 - 25) = -0.4/50 = -0.008

c.) For 100 ≤ d ≤ 200;
ΔT/Δd = (6.00 - 5.10)/(200 - 100) = 0.9/100 = 0.009
