Which of the two A and B has greater velocity in the following? Give reason for your reply.



Answer :

A has greater velocity.


Explanation:


The slope of distance and time graph gives the velocity.


Since,


Velocity =


The formula for slope of any graph line is the ratio of change in value of y-axis to the change in value of x-axis.


x = t


y = s


so, slope =



Thus from the above diagram, if we estimate the change of distance on y-axis to the change of time on x-axis of both A and B, then we will find that the slope corresponding to A is greater as change in distance in A is more than that of B, if we keep the change in time constant.


Hence A has higher velocity than B
