Some starter code

#include<lcd.h>

float numberofpulsesperrotation = 8.0;
float wheeldiameter = 1; // assume 1 meter BIG wheel
float wheelsize = 3.14159265 * wheeldiameter; // or 2* PI * radius)

void setup()
{
...
}

void loop()
{
  ...
  if (timetorefreshscreen())
  {
    float distance = numberofpulses * wheelsize / numberofpulsesperrotation;
    float speed = 60 * wheelsize * numberofpulsesinlastminute/numberofpulsesperrotation/1000; // KM/h
    lcd.print(distance);
    lcd.print(speed);
  }
}

bool timetorefreshscreen()
{
... 
  return true;
}

What code do you have sofar?
