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

What is average speed?

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

  • Let his average speed in the second half = x

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.
