When a car is moving in a straight line at a constant speed of 20 meters per second, it means that every second, the car covers a distance of 20 meters. If this car starts 200 meters away from its destination, we can determine how long it will take to reach the destination by dividing the total distance by the speed.
In this case, the calculation would be:
Time = Distance / Speed
Here, the distance is 200 meters and the speed is 20 meters per second. So, we can plug in the numbers:
Time = 200 meters / 20 meters per second = 10 seconds
This means that it will take the car 10 seconds to reach its destination. The constant speed ensures that the car will maintain this rate of travel until it covers the full 200 meters, arriving at the destination precisely in 10 seconds.
