Default RPM and speedometer does not match?

I noticed lately on my 1995 GSR that my RPM does not match my speedometer. Here's what I noticed, when my rpm is 4k the reading on speedometer is only 55mph, but I believe that my speed is 70mph. Then around hour and half of driving, my speedometer reading is 70mph with 4krpm. What is wrong with my car?
