A rancher needs to travel from a location on his ranch represented by the point (12, 4) on a coordinate plane to the point (9, 2). Part A: Assume that each unit on the plane represents one mile. What is the shortest distance between the two points (rounded to the nearest tenth of a mile)? Part B: It takes the rancher 10 minutes to travel one mile on horseback. How long will it take him to travel the entire distance between the two points (rounded to the nearest minute)?
