Answer:
The correct answer would be 43 km/hr.
Speed is defined as the rate at which a person or a thing is moving.
It can be calculated by dividing total distance traveled by the total time taken to cover that distance.
Speed = Distance / time
It is provided that a car traveled 520 kilometers in 12 hours.
So, the distance = 520 kilometers
Time = 12 hours
Speed = 520/12 kilometers per hour
= 43.33 kilometers per hour.
