Thanks AWOL and johncc

I got it to work

#include <Servo.h> 
  int sensorpin = 3;
  int speed0 = 91;
  int speed1 = 61;
  int speed2 = 111;  
  int speed3 = 71;
 
Servo leftwheel;
Servo rightwheel;

void setup()
{
    pinMode(3,INPUT);
    leftwheel.attach(8);
rightwheel.attach(9);
leftwheel.writeMicroseconds(50);
rightwheel.writeMicroseconds(50);
}

void loop()
{
  if ( digitalRead(sensorpin)!=HIGH){
  leftwheel.write(speed1);
  rightwheel.write(speed2);
 
  
}

  else if ( digitalRead(sensorpin)==HIGH){
  leftwheel.write(speed3);
  rightwheel.write(speed3);
  
  }
}
