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

integrating

kx^2 = t + c

? 2 unknowns ? or what am i doing wrong here
