Explanation / Answer

For Point 1-3-

Average speed = total distance/ total time = 25 + 15/ 1+ 0.5 = 26.67 km/hr.

Average velocity = Final position - Initial position/ Change in time = 40-30 / 1.5 - 0 = 6.67 km/hr.

For point 3-5 -

Average speed = total distance/ total time = 25 + 5/ 1.5 + 2 = 8.57 km/hr.

Average velocity = Final position - Initial position/ Change in time = 60-30 / 5 - 1.5 = 8.57 km/hr.
