The average speed of the motorist in the second half of the journey is determined as 7 km/h.

<h3>What is average speed?</h3>

The average speed of an object is the ratio of total distance to total time of motion.

21 = (35 + x) / 2

35 + x = 42

x = 42 - 35

x = 7 km/h

Thus, the average speed of the motorist in the second half of the journey is determined as 7 km/h.
