HTML: How to align left, center, and right footer phrases. Bootstrap

I'm having issues aligning my footer text in a straight line. I'm a beginner here so I apologize if this question is redundant! See below:

I need all three of those lines, to be in a straight line.

My professor teaches a grid method, but that's not working for me at the moment. Any suggestions?

Here is my code:

<html>
<head>
<meta charset="UTF-8">
<meta name="robots" content="noindex"> 

<style>

img {
  display: block;
  margin-left: auto;
  margin-right: auto;

}
</style>
<title>Custom Error Page</title>

</head>

<body>

    <div class="card">
        <div class="card-header" style = "background-color: #d8edd0">
            <h1><center>Page Not Found</center></h1>
            <h3><center>Something went wrong!</center></h3>
        </div>

    <div class="card-body">     
        <img src = "images/404.png" alt = "404" style="width:50%;"/> 
        <p style="text-align:center;">Perhaps you would like to visit the following pages:</p>
