How long will 3200mah and 6000mah lipo last

Title says it all

For less than casual (half speed) brushless 3100kv 60a ESC how long will a 3200mah 3s lipo last and 6000mah ? 
 

I'm talking just slow driving in my back garden.

I guess it depends on so many things but I prefer 2 x smaller to one bigger.

 

Slow driving I am getting over 5km from a TRX4 and a Wraith out of a 5200mah. That’s about an hour to an hour and 10 min.

Cheers thank you.
