plz mark my answer as brainliest

Step-by-step explanation:

here,

the truck travels in 3 hours = 40×3 km =120km and retuns same distance in 10km/h speed.

So it travels back in 120÷10 hours =12 hour

now, its total travel distance is (120+120)km =240km

and its total time spent (3+12)hour =15 hours

so its average speed was = 240÷15 km/h

=16km/h
