Question

You are part of a team to go on a geological dig site and will arrive at the airport shown in the diagram below. Note, the diagram is NOT drawn to scale. As shown, there are three possible routes to hike to the dig site and all paths are on the same elevation. All distances are given in miles. The direct route, AD, is 40 miles long but last week two geologists were attacked by grizzly bears on that route. Most of the path from B to D is through thick brush. The remaining paths have no known hazards at this time. 1) Determine the lengths of the other two routes (ABD and ACD). Identify any formula or law you are applying. Clearly show each step in solving the equation. Use correct units. 2) Which of the three routes would you choose and why? Justify your answer. You should give more than one reason for your decision and list any assumptions that you make. Remember that you are giving your convincing argument for selecting a particular route. Your answer must be written in complete and grammatically correct sentences
