Features: When learning each speed calculation method, you might find it a bit troublesome and think it's faster to calculate step by step using the usual methods. At this point, please remember the two lines of poetry from the ancients: "To see a thousand miles, climb one more story." Every time you overcome a learning difficulty, you will gain infinite joy. When you first learn a speed calculation method, your calculations may not be fast, and you might even make mistakes. At this point, please remember the saying "Practice makes perfect." You are not yet proficient, so you need to do more practice and look for exercises to practice anytime, anywhere. Each section of this book has exercises, and the answers are provided at the end of the book.
