Conversion of root mean square or interval velocity into average

[taimur]

I really ain't sure whether my problem is mathematical or related to Physics but i most probably think it has a mathematical solution.

I am have a situation where I have subsurface seismic velocity windows at certain Depth points. In the window I have been given the two-way time in seconds and root mean square velocity (Vrms). I have used the DIX equation to convert Vrms into interval velocity (Vint) but i need average velocity for depth conversion i.e time into depth.

I am giving you the data at a particular CDP. Please tell me the relationship that can be made between the given quantities to find the required (average velocity).

time----Vrms----Vint
0-----1500----1940
0.31----1940----2058
0.62----2000----2510
0.85----2150----3821
0.97----2420----3312
1.15----2580----5403
1.23----2850----4399
1.35----3020----4353
1.96----3490----5286
2.57----3990----5403
5------4730
