Schedule job in laravel time interval

I have three schedule job every hour in Kernel.php like below:

$schedule->command('get:twitter')->cron('* 1 * * * *');
$schedule->command('get:facebook')->cron('* 1 * * * *');
$schedule->command('get:googleplus')->cron('* 1 * * * *');

I want to run this three schedule in some time interval like below:

$schedule->command('get:twitter')->cron('* 1 * * * *');//after 1 hour
$schedule->command('get:facebook')->cron('30 1 * * * *');//after 1.30 hour
$schedule->command('get:googleplus')->cron('45 1 * * * *');//after 1.45 hour

Is this possible in laravel 5.1
