The concentration of a drug in the bloodstream C(t) at any time t, in hours, is described by the equationC(t)=100t/t^2+25where t=0 corresponds to the time at which the drug was swallowed. Determine how long it takes the drug to reach its maximum concentration. It will take hours until it reaches its maximum concentration.
