You and a friend work in buildings four equal-length blocks apart, and you plan to meet for lunch. Your friend strolls leisurely at \(1.2 \mathrm{~m} / \mathrm{s}\), while you like a brisker pace of \(1.6 \mathrm{~m} / \mathrm{s}\). Knowing this, you pick a restaurant between the two buildings at which you and your friend will arrive at the same instant if both of you leave your respective buildings at the same instant. In blocks, how far from your building is the restaurant?
