the displacement time graph for the two particles A and B are straight lines inclined at angles of 30 and 45 degrees with the time axis.what is the ratio of the velocities VA : VB ?

PLZ ANS AS SOON AS POSSIBLE ...........TOMMOROW IS MY EXAM

In a displacement time graph slope of the curve at a point gives the velocity at that point in displacement time graph.

Diagram below explains the statement given above

According to your question the displacement time graph is shown below:
