  distance = 500km

  time taken = 10hrs

  speed = distance/time

  = 500/10

  =50 km/h

  To convert quantities from km/h to m/s, multiply the said quantity by 5/18{simplified form of 1000/3600}

  According to question : 50 x 5/18

  = 250/18 m/s

  = 13.8 m/s

  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.
