    It's hard to see but you may have made a mistake after this line:

    (1/2)ln|2v-450|...

    Where did the (1/2) go in the next line?

    I wrote it in pencil but here's the answer:

    1/2ln(2v-450)= -1/15t + c
    2v - 450 = Ae^-1/15t
    V= A/(2^-1/15t) + 225

    Let v= 300 and t=0

    >> A= 150

    Let t=15

    >>> V=27.59 + 225= 253
