5 units

Explanation:

Let us make a graph of speed(v) vs time(t)

so,our equation becomes v = |t-3| (because speed is never negative)

so,our table becomes,
at, t=0, v=3
t=1, v=2
t=2, v=1
t=3, v=0
t=4, v=1

Now putting the values in the graph, we get a curve.

we know that distance = area under( speed-time) curve

so,area under the curve we obtained is,
1/2*3*3 + 1/2*1*1 or, 5 units
