You can put this solution on YOUR website!
Use:
+d+=+r%2At+
[ miles ] = [ miles/hr ] x [ hrs ]
------------------------------
Convert 6 3/4 to a fraction:
+6+=+24%2F4+
+24%2F4+%2B+3%2F4+=+27%2F4+
-------------------------
+d+=+58%2A%28+27%2F4+%29+
+d+=+1566%2F4+
+d+=+391.5+
---------------
They drove 391.5 mi
hope this helps
