Answer:
Answer: Since the slope of the displacement-time graph of uniform motion in one dimention represents the velocity of the object, hence the line showing greater slope in graph corresponds to greater velocity of the object. Therefore OB represents greater velocity.

Answer:
Since the slope of the displacement - time graph of uniform motion in one dimension represents the velocity of the object, hence the line showing greater slope in graph corresponds to greater velocity of the object .
Therefore OB represents greater velocity .
Ratio of two velocities
UA/UB = tan30°/tan60°
= 1/√3/√3
= 1/3
