Answer:

3.06km/hr

Explanation:

Average speed (km/hr) = distance (km)/time(hr)

Total average speed = 152/10

= 15.2km/hr

For the first 85km which he drove for 7hours, average speed = 85/7

= 12.14km/hr

His average speed in km/h for the remaining journey will, therefore, be:

15.2km/hr - 12.14km/hr

= 3.06km/hr
