A car move at an average speeds of 30km/s,how long does it take to cover 200 meters?
time = distance/speed, so
200m / (30km/s) = 0.2km / (30km/s) = 0.2/30 s
To calculate the time it takes for a car to cover a given distance, you need to use the equation:
Time = Distance / Speed
In this case, the distance is 200 meters and the speed is 30 km/h. However, we need to convert the speed to meters per second to make the units consistent.
To convert from kilometers per hour (km/h) to meters per second (m/s), we need to divide the speed by 3.6 since there are 3,600 seconds in an hour (60 seconds × 60 minutes).
So, let's convert the speed:
Speed = 30 km/h ÷ 3.6 = 8.33 m/s (rounded to two decimal places)
Now, we can plug the values into the equation:
Time = Distance / Speed
Time = 200 meters / 8.33 m/s
Calculating this will give us the time it takes for the car to cover 200 meters.
