We know that velocity =displacement /time
And from the graph we get that it shows velocity
So slope =tan theta
TanVa/tan Vb
Tan 30/tan 60=1/root 3

We know that in Displacement time graph. Slope of the line represents the velocity in that time period.
For motion O to A, slope of line OA,
v₁ = tan30°
v₁ = 1/√3
For motion O to B, slope of line OB,
v₂ = tan60°
v₂ = √3
Hence,
v₁/v₂ = (1/√3)/√3
v₁/v₂ = 1/3
Note:- Slope of a line is given by m = tanФ, where Ф is the angle between line and x- axis
