Extreme heat applied to a colony of microorganisms causes the size p of the colony, measured in grams, to decrease according to the exponential decay model dpdt=−0. 4p, where the time t is measured in hours. The size q of a second colony of microorganisms, also measured in grams, decreases at the constant rate of 1 gram per hour according to the linear model dqdt=−1. If at time t=0 the first colony has size p(0)=2 and the second colony has size q(0)=3, at what time will both colonies have the same size?.
