Answer:

9.6 km

Explanation:

The last third of the trip is 3200 meters. The first two thirds can be calculated by multiplying that value with two:

$d_(1)=3200*2\\d_(1)=6400m$

The total distance is the sum of the two thirds and the last third of the trip:

$d_(1) +d_(2)\\=6400+3200\\=9600m$

To convert the distance to kilometres, the value should be divided by 1000:

(9600)/(1000)=9.6km
