Look at the definition of a Wiener Process then:

Group the terms together into non-overlapping time pairs:

.........

.........

Then the three bracketed terms are zero mean Guassian distributed and independent,

with variances 4, 1 and 2. So the required distribution is Gaussian with mean and

variance
