    You need to show us your attempt. Are you familiar with the quotient rule and so on?

    FYI, you wrote

    [tex]
    f(t)=\frac{100t}{2t}+15
    [/tex]

    Is that what you meant? If you meant to write

    [tex]
    f(t)=\frac{100t}{2t+15}
    [/tex]

    then you need to use parentheses.

    I'm almost certain he means the later, or the answer is pretty basic in fact it barely requires calculus.:smile:

    [tex]
    f(t)=\frac{100t}{2t+15}
    [/tex]

    Have you tried the quotient rule? Please show working?
