1. You are an engineer and you know that the time (T) it takes to build a bridge varies directly as the length (L) of the bridge and inversely to the number of workers (W). And it takes 120 days to build a 20 m bridge with 10 workers. Given the following conditions, solve the following problems: A. Representation 1. Using symbols 2. Using equation B. What is the constant of variation? C. How long will it take to build the bridge if 2 workers will be out?
