To solve the problem, we need to find the path that the person should follow to reach the line \(6x - 7y + 8 = 0\) in the least time. This path will be the perpendicular distance from the point of intersection of the two given lines to the third line. ### Step-by-Step Solution: 1. **Find the Point of Intersection (P) of the Two Given Lines:** The equations of the two lines are: \[ 2x + 3y + 4 = 0 \quad \text{(1)} ...
