How long does it take to lvl from 20 to 30

I used to play Dota 2 a lot so im fairly good at Mobas and I started playing pvp instead of bots. I won a lot and now my que timer is like 4-10 minutes long. I started back playing bots but how long will it take to level up to 30 because its hard to find games right now and I'm tired of playing against bots.
