The store display rotates 40 times every half hour meaning that it will rotate 80 times every hour. To find how many times it will rotate in 4 hours, you can do 80 times 4. This is 320 rotations.

Learning something new can be a scary experience. One of the hardest things I've ever had to do was learn how to swim. I was always afraid of the water, but I decided that swimming was an important skill that I should learn. I also thought it would be good exercise and help me to become physically stronger. What I didn't realize was that learning to swim would also make me a more confident person.
New situations always make me a bit nervous, and my first swimming lesson was no exception. After I changed into my bathing suit in the locker room, I stood timidly by the side of the pool waiting for the teacher and other students to show up. After a couple of minutes the teacher came over. She smiled and introduced herself, and two more students joined us. Although they were both older than me, they didn't seem to be embarrassed about not knowing how to swim. I began to feel more at ease. we took it slow, till i learned how to do the breaststroke and the dolphin. soon, i was racing my brother and winning.
