Write the unit rate. Round to the nearest tenth if necessary 20. 150 pages in 3 hr . 21. 1,310 mi. in 5 days 22. \( \$ 240 \) for 15 piano lessons 23. \( \$ 98 \) for 5 books

For the first scenario, to find the unit rate of pages per hour, we divide 150 pages by 3 hours. This gives us 50 pages per hour, which is a straightforward calculation that shows just how many pages you would read if you maintained that pace! In the second scenario, we need to find the miles per day by dividing 1,310 miles by 5 days. That calculates to 262 miles per day—perfect for planning a road trip where you want to make sure you’re covering plenty of ground each day while still having fun! Now let’s tackle the third case. To find the cost per piano lesson, we divide \$240 by 15 lessons. The result is \$16 per lesson, which gives you a great benchmark for comparing whether this lesson rate is right for your budget or if it’s time to start looking for some deals! Lastly, for books, we calculate the cost per book by dividing \$98 by 5 books. This provides us with \$19.60 per book, so you know exactly how much each literary adventure will cost. Now you can hit the bookstore or library with confidence!
