You paint 13 of a wall in 14 hour. At that rate, how long will it take you to paint one wall?
I assume you mean 1/13 of a wall.
This means in 14 hours you paint one piece of a wall that is divided equally into 13 sections. If we paint all 13 of those sections, we get that 13 14 = 13 10 + 4*13 = 130 + 52 = 182 hours.
