suppose i have plotted a point on 2d graph and i know the avg speed of this point and after one minute I wish to know the coordinate of that point on 2d

Average speed doesn't have a direction component, so it is theoretically not possible to calculate the 2D coordinates.

X=0;         %Initial X position
Y=0;         %Initial Y position
Xspeed=5;    %Speed in X direction, times 60 if you want it to be in minutes.
Yspeed=3;    %Speed in Y direction,  ##
nseconds=10; %Number of seconds/minutes it runs
figure
grid on
hold on
for it=1:nseconds
Plot(X+it*Xspeed,Y+it*Yspeed,'o')
end

This is what you want I think

thomas it shows node in diagonal but some time X coordinates increase and y coordinates are decrease and vice versa.than mostly cases node not in diagonal.
