C error, double expects double*

Just started using C and I'm getting 1 error on my code:

#include <stdio.h>
#include <stdlib.h>

int main()
{
    //declare variables
    double speed = 1.4, hours, totalYards;

    //prompt user to enter amount of hours
    printf("Enter the amount of hours: ");
    scanf("%lf", &hours);

    //calculate amount of yards taken
    totalYards = speed * hours;

    //display result to user
    printf("The total amount of yards is %.2f", &totalYards);

    return 0;
}

and the error is

warning: format '%f' expects argument of type 'double', but argument 2 has type 'double *' [-Wformat]|

on the last printf.

Change 

 printf("The total amount of yards is %.2f", &totalYards);

to 

  printf("The total amount of yards is %.2f", totalYards);

You were passing a pointer object (type double *) but f requires you to pass a value of type double.
