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.
To determine the speed of a body from a distance-time graph when the body starts from rest, you can find the slope of the graph. The slope of a distance-time graph represents the speed of the body. A steeper slope indicates a higher speed, while a shallower slope indicates a lower speed.
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).
the slope of distance time graph gives us velocity but when the body is at rest it will be zero
If we know the speed and the time taken for a body to cover a distance, then we can find the distance covered by it as follows: distance=speed*time
To determine the speed of an object, you need to know the distance the object has traveled and the time it took to travel that distance. Speed is calculated by dividing the distance covered by the time it took to cover that distance.

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.

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.
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).
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.
It is moving at a constant speed with no acceleration nor decceleration
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.
the slope of distance time graph gives us velocity but when the body is at rest it will be zero
If speed changes, then the speed/time graph has up/down curves in it.
yes,displacement is the shortest distance covered by a body,so distance covered by a body may be greater than the displacement.
If we know the speed and the time taken for a body to cover a distance, then we can find the distance covered by it as follows: distance=speed*time
