A mirror in an amusement park shows a vertical image of anyone 2.5 m in front of it. If the image is three times the person's height, how far from the mirror are the images formed, and what kind of images are they?

• d1 = 5.7 m, real, inverted, bigger
• d1 = 7.5 m, real, straight, bigger
• d1 = - 5.7 m, real, inverted, bigger
• d1 = - 7.5 m, virtual, inverted, bigger
