To find the car’s speed, we can divide the distance traveled by the time taken.

Given:

Distance traveled = 500 km

Time taken = 10 hours

Speed = Distance / Time

Speed = 500 km / 10 hours

Speed = 50 km/hr

Therefore, the car’s speed is 50 km/hr.

To convert this speed to m/s, we need to remember that 1 km/hr is equal to 1000 m/3600 s.

Speed in m/s = (Speed in km/hr) * (1000 m/3600 s)

Speed in m/s = 50 km/hr * (1000 m/3600 s)

Speed in m/s = (50000 m / 3600 s)

Speed in m/s ≈ 13.89 m/s

Therefore, the car’s speed is approximately 13.89 m/s.
