The average speed of the car is 25 m/s.
Explanation:
The average speed of an object is the total distance traveled by the object divided by the time to cover that distance. it is a scalar quantity.
Total distance covered = 10 km+10 km = 20 km
total time taken during journey = 20 min + 30 min = 50 mins = 0.8 hrs
we know that
average speed = total distance covered / total time taken
= 20 /0.8 = 25 m/s
