If I can skatech 8 papers in ten hours how long will it take to sketch 16 papers?

Answer 1

If you can sketch 8 papers in ten hours, then your rate of sketching papers is 8 papers / 10 hours = 0.8 papers per hour.
To sketch 16 papers at this rate, it would take 16 papers / 0.8 papers per hour = <<16/0.8=20>>20 hours. Answer: \boxed{20}.
