Answer:
Bear in mind that there is no mention of the direction of this movement in the problem, and we take speed as a scalar quantity, speed refers to the rate at which an object covers distance. It is the magnitude of velocity and does not include direction. In other words, speed tells us how fast an object is moving without specifying the direction.
To find the distance traveled by the vehicle in 400 seconds when moving at a speed of 20 meters per second, we can use the average formula:
Next, we have to enumerate the given quantities:
Speed = 20 meters per second
Time =400 seconds
At this point, we could cancel out the unit of time (seconds) and the remaining unit will be meter (m), which gives us 8000 meters.
The formula for distance is the product of speed and time. When an object travels at a constant speed, the distance traveled is equal to the speed multiplied by the time.
This calculation yields the result of 4000 meters.
So the answer is letter C 4000 meters.
