Which is the equation of an ellipse with directrices at x = ±4 and foci at (2, 0) and (−2, 0)?

The track team ran a mile and a quarter during their practice how many kilometers did her team runs?

Find the equation of the ellipse with the following properties. the ellipse with foci at (0, 6) and (0, -6); y-intercepts (0, 8) and (0, -8).edit: the answer is x^2 over 28 + y^2 over 64 = 1
