It’s 1.5m (5ft). It scales up with strength and caps at 4m (13ft). So yeah, if you want to be a barbarian/fighter or some big burly half orc with 17 str then sure you can push a 3ft tall gnome 12ft. But you’re saying “6m+” and “15-20ft” as if it’s standard or even possible. It’s not.
Yes it is silly to make it a bonus action and I hope they patch it to full action. 
Dude you keep making numbers up that are way higher when the numbers are readily available
