57 kilometers &lt;b&gt;&lt;i&gt;per hour&lt;/i&gt;&lt;/b&gt; means exactly what it says.  57 km the first hour plus 57 km the second hour -- and so on through the seventh hour.  If you think about it for a minute, you will recall that we have a little arithmetic shortcut for adding 57 seven times.  Hint:  it is called multiplication.
