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.
