A = P \left(1 + \frac{r}{n}\right)^{nt}
13000 = 12000 \left(1 + \frac{0.055}{2}\right)^{2t}
1 + \frac{0.055}{2} = 1.0275
13000 = 12000 \cdot 1.0275^{2t}
\frac{13000}{12000} = 1.0275^{2t}
1.0833 = 1.0275^{2t}
\ln(1.0833) = \ln(1.0275^{2t})
\ln(1.0833) = 2t \ln(1.0275)
t = \frac{\ln(1.0833)}{2 \ln(1.0275)}
t \approx 1.48 \text{ years}
