My friend Amy visits her grandparents every weekend. Her grandparents live about twenty kilometers away from her home. It’s easy for her to get to her grandparents’ home. She usually leaves home at about eight o’clock. First, she rides a shared bike to the subway station. It usually takes her ten minutes. And then, she takes the subway and it takes her about thirty minutes. At last, she walks to her grandparents’ home for five minutes.She likes to take the subway, because it runs quickly.
