What is the speed of a car that travels a distance of 520 kilometers in 12 hours? 0.43 km/hr 0.023 km/hr 62.4 kmhr 43 km/hr

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.
