How fast am I going?

3rd gear 5500 rpm with 3.42 gears. Speedo only goes up to 100 and my speed limiter is 128 so it is somewhere in between that but i dont know how to figure it out.

if it concerns you, than while you are in 3rd gear at a much lower speed, see how many mph it raises per 1000rpms and just do the math. I think that would work.
