Question 1 Report
A car moves at an average speed of 30kmh\(^{-1}\), how long does it take to cover 200 meters?
Answer Details
To find the time taken by the car to cover 200 meters, we need to use the formula:
time = distance ÷ speed
Here, the distance is 200 meters and the speed is 30 km/h. However, we need to convert the speed to meters per second (m/s) to get the answer in seconds.
We know that 1 km = 1000 meters and 1 hour = 3600 seconds.
So,
30 km/h = (30 x 1000) m / (3600 s) = 8.33 m/s (approx.)
Now, we can substitute the values into the formula:
time = distance ÷ speed = 200 m ÷ 8.33 m/s ≈ 24 seconds
Therefore, the car takes 24 seconds to cover 200 meters.
Hence, the answer is 24 sec.
