You should look at the requirement for accuracy. You may need many pulses per revolution.
When travelling fast, you can count the number of pulses in a certain time, you will need a lot of pulses.
When travelling slow, you will need to measure the time between pulses.

Ok I think this can be done as follows. You are going to need:

A clock generator x 1
A pulse generator x 1
And associated timing components.

AND gates
4 bit counter x 2
Quad flip flop x 2
BCD to seven segment display driver x 2
And current limiting resistors for the display.

Good Luck
Adam
