A directed line segment on a gridded map shows the path of a hot-air balloon from A(0, 0) to B(8, 4). Each grid unit represents 1 mile. The balloon traveled at a constant speed of 20 miles per hour. Point V divides AB in the ratio 6 to 2. What are the coordinates of V? Round to the nearest tenth if necessary. Mary states that the distance from A to V is 6 miles. What is Mary’s mistake? What is the correct distance?
