    Undergrad When Daughter Activity Becomes Equal To Parent Activity

    I'm sorry. The problem didn't display as typed. Ill try this way. Its: e^-0.0495t=0.0289/0.0289-0.0495^(e-0.0495t - e-0.0289t) Thank you Thetes for your assistance. The answer is 26 minutes but I cannot seem to solve and arrive at this value. What am I doing wrong?

    Undergrad When Daughter Activity Becomes Equal To Parent Activity

    Hi. New here (Again). I'm having trouble with solving transient equilibrium problem e-0.0495t= 0.0289 (e-0.0495t- e-0.0289t) _____________ 0.0289-0.0495 I know the answer but can't seem to make this work. Maybe I'm messing up my order of op.
