After the first minute has past, creeps start spawning in waves of 6, and take 30 seconds to reach the lane. Additionally, every 30 seconds you get a new wave of 6, with a seige minion every 3 waves, or 19 creeps total every minute and a half. By ten minutes, you can have 76 creeps from farming one lane, and nothing else. If you farm other sources, such as lanes pushing to your tower that no one is guarding, you can get even more, let's say roughly half of what you'd earn from sticking to one lane, on top of that, in about the same time. So around 114 creeps every 9 minutes is an everage amount to shoot for. If you get higher, good for you!
