(Solution Download) If you are too close to a radio tower you


If you are too close to a radio tower, you will be unable to pick up its signal. Let the center of a town be represented by the origin of a coordinate plane. Suppose a radio tower is located 2 mi east and 3 mi north of the center of town, or at the point (2, 3). A highway runs north-south 2.5 mi east of the center of town, along the line x = 2.5. Where on the highway will you be less than 1 mi from the tower and therefore unable to pick up the signal?
