After a meal, a person's blood glucose concentration rises to \(9 \text{ mmol L}^{-1}\). Normal fasting level is \(5 \text{ mmol L}^{-1}\). Insulin secretion increases glucose uptake at a rate proportional to the excess glucose above normal with constant \(k = 0.8 \text{ mmol L}^{-1}\text{ min}^{-1}\). Simultaneously, glucagon secretion reduces uptake at a rate proportional to the same excess with constant \(g = 0.2 \text{ mmol L}^{-1}\text{ min}^{-1}\). Assuming no further glucose intake, how many minutes will it take for the glucose concentration to fall to within \(0.1 \text{ mmol L}^{-1}\) of the normal level? Give your answer to one decimal place.
