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.

A distance-time graph for a body starting from rest how will you determine the speed of a body from this graph?
The instantaneous slope at any point along the graphed line is the speed at that point in time.
What is the slope in the distance time graph when the body is at rest?
the slope of distance time graph gives us velocity but when the body is at rest it will be zero
Is the distance covered by a body may be greater than the magnitude of displacement?
yes,displacement is the shortest distance covered by a body,so distance covered by a body may be greater than the displacement.
What will you say about motion of body if distance time graph is straight line having constant angel with time axis?
If the distance/time graph is a straight line that makes a constant angel with the time axis, then the body's speed is constant, and is equal to the slope of the straight line (tangent of the constant angel).
Simple definition of distance in trem of physics?
distance= (speed) multiplied by (time)i.e. the total length of path covered by a body in moving from one point to another
Does the speed-time graph show the distance covered by a body in unit time?
Not always. A proper speed-time graph will show the distance covered by a body in unit tme - which is how instantaneous speed is defined. The height of the graph at the point in time that is of interest, will give the distance covered in unit time - at that time. If the graph is not a straight line then the answer is given by the average value of the height of the graph over an interval going half-a-unit of time either side of the point of interest. However, speed-time graphs are often related to corresponding distance-time graphs. In such a case, the graph records the velocity of a body in the direction towards or away from the origin at various points in time. It takes no account whatsoever of any motion in a transverse direction. So the component of velocity in a transverse direction is lost. Thus, suppose O is the origin and I am at position P. If I move at right angles to OP, the speed-time graph will not show me moving at all.
Sketch a distance time graph as when a body is at rest and when a body is moving with constant speed?
about a hour

The instantaneous slope at any point along the graphed line is the speed at that point in time.
Sketch a distance-time graph for a body starting from rest how will you determine the speed of a body from this graph?
It is not possible to sketch anything using this browser. The speed of a body cannot be determined from a distance-time graph. The slope of the graph is a measure of the radial velocity - that is the speed directly towards or directly away from the starting point. However, there is absolutely no information of any motion in a transverse direction. Since motion in this direction cannot be assumed to be 0, the distance-time graph cannot be used to determine speed.
Why is it not possible for any part of the distance-time graph of a body to be a straight-line segment parallel to the distance axis?
BecAuse that would mean it is going an infinite speed. The slope of a distance time graph is the objects velocity or speed. If there is a line parallel to the distance axis, there is a vertical line. The slope of a vertical line is infinite. It is not possible to go an infinite speed.
What can you say about the motion of a body if its distance-time graph is a straight line?
It is moving at a constant speed with no acceleration nor decceleration
What would be the shape of a speed time graph of a body moving with variable speed?
If a body is moving with variable speed, then the only thing you can say aboutits speed/time graph is that the graph is not a straight, horizontal line.
What is the slope in the distance time graph when the body is at rest?
the slope of distance time graph gives us velocity but when the body is at rest it will be zero
What would be the shape of a speed - time graph of a body?
If speed changes, then the speed/time graph has up/down curves in it.
Is the distance covered by a body may be greater than the magnitude of displacement?
yes,displacement is the shortest distance covered by a body,so distance covered by a body may be greater than the displacement.
Is the distance covered by a body may be greater than a magnitude of the displacement?
yes,displacement is the shortest distance covered by a body,so distance covered by a body may be greater than the displacement.
What would be the shape of speed time graph of a body moving with variable speed?
Distance-time graph will show a straight line with a positive slope. Speed-time graph will show a horizontal line at the uniform speed. Acceleration-time graph will show a horizontal line at a = 0.
