    Is this homework?

    Without some background, I don't see that there's enough information to answer the question.
    Known value with condition one is determined (example: at 5 minutes , a value of 0.204 is obtained).
    The value at 5 minutes is not 0.204 in either series.

    If the value was .213, is there a way to do this?

    I'm not hedging, I just don't understand the problem.
