A truck travels north at a constant speed on a straight North-South
covering a distance of 25 km in 30 minutes. The driver realizes that
he forget to pick up a package, and turns the truck around, and
heads straight back to the original place. It took him 20 minutes on
the return trip. Find the displacement, average speed and average
velocity for the entire trip.

The driver first moves from North to South and than again to North so it's displacement will be zero.
The average speed=total distance/total time
=the driver travel from North to South and again back to North so it's total distance will be 25+25=50km
=total time =20+30=50mim
average speed=50/50
average speed=1km/minutes
average velocity=displacement/time
average velocity=displacement is zero we have seen above
time is 50minutes
average velocity=0/50
average velocity=0
If you find the above answer correct and my way easy please follow me and also comment in the box .I will try to give answer as soon as possible.Also rate it please
