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 â‰ˆ 13.89 m/s

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