is more like it!
Mind, now I look at it I'm not sure why ...
The rate at which the temperaturex of a liquid decreases is inversely proportional ites temperature at time t. write down a differential eq and solve it. given that the temp of the liquid increases from 20 to 20.5 in 2 seconds find temp of body after 10 seconds...
Inversely proportional = 1/k
so eq would be
dx/dt = 1/kx
kx dx = dt
kx^2 = t + c
? 2 unknowns ? or what am i doing wrong here
