Answer:

96.5 km/h south

Explanation:

The average velocity is given by:

v=\frac{d}{t}

where

d is the displacement

t is the time

We have:

d = 55 km

t = 34 min \cdot \frac{1}{60}=0.57 h

Therefore, the average velocity is

v=\frac{55}{0.57}=96.5 km/h

And the direction is the same as the  displacement (south)
