A car travels distance in 330 km in 20 hours what will be it’s speed in km per hour and metre per second.

A car travels distance in 330 km in 20 hours what will be it’s speed in km per hour and metre per second. please help guys please

The Correct Answer and Explanation is:

To calculate the speed of the car, we can use the formula for speed:Speed=DistanceTime\text{Speed} = \frac{\text{Distance}}{\text{Time}}Speed=TimeDistance​

Step 1: Convert the distance and time into the desired units.

1. Speed in kilometers per hour (km/h):
   • The car travels 330 kilometers in 20 hours.
   • Using the formula for speed:
   Speed=330 km20 hours=16.5 km/h\text{Speed} = \frac{330 \, \text{km}}{20 \, \text{hours}} = 16.5 \, \text{km/h}Speed=20hours330km​=16.5km/h So, the speed of the car is 16.5 km/h.
2. Speed in meters per second (m/s):
   • To convert from kilometers per hour to meters per second, we need to convert kilometers to meters and hours to seconds.
   • 1 kilometer = 1000 meters, and 1 hour = 3600 seconds.
   Therefore, we can convert the speed in km/h to m/s by multiplying by the conversion factor: Speed=16.5 km/h×1000 meters1 kilometer×1 hour3600 seconds\text{Speed} = 16.5 \, \text{km/h} \times \frac{1000 \, \text{meters}}{1 \, \text{kilometer}} \times \frac{1 \, \text{hour}}{3600 \, \text{seconds}}Speed=16.5km/h×1kilometer1000meters​×3600seconds1hour​ Speed=16.5×10003600=4.58 m/s\text{Speed} = 16.5 \times \frac{1000}{3600} = 4.58 \, \text{m/s}Speed=16.5×36001000​=4.58m/s So, the speed of the car is 4.58 m/s.

Conclusion:

• The car’s speed is 16.5 kilometers per hour (km/h).
• The car’s speed is 4.58 meters per second (m/s).

The key point here is that converting between kilometers and meters as well as hours and seconds allows us to express the same speed in different units.
