The product of velocity and time yields distance travelled if the velocity is constant for the time in question. If velocity is not constant, one must first calculate the average velocity over a given time period before multiplying it by the time involved.

The distance traveled can be calculated by finding the area under the velocity-time graph. The slope of the graph at any point represents the acceleration of the object. The steeper the slope, the greater the acceleration.
The area under a speed-time graph gives distance because distance traveled is equal to the product of speed and time traveled. By calculating the area under the speed-time graph, you are essentially finding the total distance traveled by integrating the speed function with respect to time.
If a car travels at a constant speed of 60 miles per hour, then the graph of distance vs. time will be a straight line with a slope of 60. This means that for every hour that passes, the car will have traveled 60 miles. The equation for this line would be y = 60x, where y is the distance traveled in miles and x is the time in hours.
The area under a speed-time graph represents the distance traveled by an object. It is calculated by finding the area enclosed by the speed-time curve.
A distance-time graph can provide a pictorial indication of how far an object has moved. The slope of the graph represents the object's speed, where a steeper slope indicates faster motion. The area under the curve on the graph represents the total distance traveled by the object.
To calculate distance from a velocity-time graph, you would find the area under the curve, as this represents the displacement or distance traveled. If the graph is above the time axis, calculate the area above the time axis, and if it dips below, calculate the area below the time axis. Summing these two areas will give you the total distance traveled.
