The City Council seeks your advice on the design of street signs in your city. All the signs will be a uniform. state-mandated height, and the Council is trying to limit costs [and preserve sight-lines for the beautiful scenery}, and so they are mostly-concerned with how WIDE the signs need to be. Assuming minimum contrast values of 0.90. calculate the minimum widths of block characters on the signs such that the signs can be read from up to 200ft away by drivers with unrestricted driving licenses inTexas. Note that the city council is always short of money, and will pay for these costly signs to be only as large as necessary for legihility within this population at that distance. Please list any necessary assurn ptions in your written work and give answers in inches
