You should put 'use strict;' and 'use warnings;' here.

$line has a newline at the end.

You can split directly into a list of variables;

A for loop would be good here.

Single quotes do not allow for variable interpolation.

Do you mean to sleep between fetches? Then sleep inside the loop.

Try this (untested):
#!/usr/bin/perl
use strict;
use warnings;
my $data = "file";
my $URL = "www.cnn.com";
open (my $fh, '<', $data) or die "Error: $!";
while ($line = <$fh>){
chomp($line);
my( $c, $sleep ) = split /\s+/,$line;
for ( 1 .. $c ) {
system("wget $URL");
sleep $sleep;
}
}
