D. 1. If the length of the bridge will be doubled to make it a two-way-wide bridge, how many weeks will 16 workers build the bridge?* 2. Will the bridge be ready before the founding anniversary of the city competition to be held 4 months from now? Defend your answer. E. If the mayor of the city wants the 20m bridge to be finished by 2 months, how many workers will be needed?

Transcribed Image Text: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:
