Why is distance travelled area under the speed time graph and not speed multiplied by time?

It is speed multiplied by time only if the speed is constant. However, if the speed is variable then you can approximate the distance travelled if you chop the overall time interval into bits and use speed x time for each interval and then add these together. As you increase the number of these time intervals and decrease their sizes, you get the integral of the speed time curve. And the area under the curve is just another way of saying that.

∙ 8y agoThe area under a graph is in the units of (vertical axis) x (horizontal axis). For example, if the axes are speed versus time, the area will have units of speed x time (i.e., distance).

The distance travelled in a given time?
The distance travelled in a given time is a means of measuring the speed. For instance, at a constant 60 mph (miles per hour) means that in one hour (60 minutes) the distance travelled is 60 miles.
How can you calculate the speed in a distance time graph?
speed is the gradient under the distance vs time graph which is change in distance /change in time
What is the ratio of distance travelled to time?
It is the average speed.
How can speed be determined from a graph of distance vs time?
Slope of the graph will give you speed.
How can you get speed of an object from its distance-time graph?
The speed is the slope of the curve in such a graph.
How can you get the distance travelled by an object from its speed time graph?
multiply speed by time.
What is the physical quantity measured under a speed time graph?
If you mean 'measured by the area under the speed/time graph' then this is total distance travelled.
How do you find a speed of a wave?
speed=distance travelled by wave divided by corresponding time take or v=frequency multiplied by wavelength
Can a distance vs time graph have a vertical line?
No, because that would imply that the object travelled at infinite speed.
What does the area under a speed-time graph represent A. acceleration B. average speed C. deceleration D. distance travelled?
deceleration or negative
The distance travelled in a given time?
The distance travelled in a given time is a means of measuring the speed. For instance, at a constant 60 mph (miles per hour) means that in one hour (60 minutes) the distance travelled is 60 miles.
How do you get average speed?
the formula of average speed is a distance travelled divided by time v= distance travelled /time elapsed
How is speed defined?
The distance travelled divided by time. Distance/time = speed
How can you get speed and distance covered by a body from distance time graph?
Distance you read off directly from the graph. Speed is the rate of increase of distance, so it is the slope (gradient) of the graph.
Could you find the distance somebody travels if you know the rate of speed?
No, you would also need to know the time spent travelled. Distance equals rate multiplied by time, or D=RT.
How is a distance- time graph different than a speed time graph?
The variable plotted along the vertical axis is the distance in the first case, speed in the second. The gradient of (the tangent to) the distance-time graph is the speed while the area under the curve of the speed-time graph is the distance.
How can you calculate the speed in a distance time graph?
speed is the gradient under the distance vs time graph which is change in distance /change in time
