#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#
