The required power goes as the cube of the velocity. You will require about 70% more power to drive at 20 mph than 24 mph. Reducing your speed will increase your range considerably.

Battery drain is fairly consistent at 7 miles per 10% of battery with a cruising speed of 24. Allowing for never going below 10% charge, my max range is in the 60-65 mile range.
Folks saying they can go 60 miles on a 100ah battery seems far fetched. I don't care how well engineered the cart is. My guess is that their speedometer is not set correctly and is not showing the correct mileage. I agree with the poster that offered $100 to see it done in real life - I would come to watch and document - as an engineer, I don't think it's possible.
