slope of position time graph gives velocity i.e v=dx/dt=tan theta va/vb=tan 30/tan 60=1/3

"Answer: Slope of position time graph gives velocity that is
v=dx/dt=tan theta
va/vb = tan30 / tan 60 = 1/3
Explanation:
The principle is that the slope of the line on a position-time graph is equal to the velocity of the object.
If the object is moving with a velocity of +4 m/s, then the slope of the line will be +4 m/s.
