Since you are a visual learner, draw and label a diagram!
That includes both the ellipse and the line joining (-4, -8) and (6, 12).
Determine the equation of the line between (-4, -8) and (6, 12).
Use the two-point form from Algebra 1.
Determine the points of intersection (two!) between the line and the ellipse.
Determine the distance from (-4. -8) and the left point of intersection
Determine the distance between (-4, -8) ad (6, 12).
Determine the distance between the right point of intersection and (6, 12).
Use the three distances with the related rates to determine the travel time in each of the three segments.
Add the three times for the total time of the trip.
