Q: Alex is working on a science project and has taken pictures of all of the plants in a park near her home. She wants to find out how many of each plant she has pictures of, but she has 960 pictures, and counting them all will take her a long time. Her teacher suggested she use a program on the computer that can automatically tell her what plant is in each picture and count them for her. It will take the program 2 minutes to process each picture. How many hours will it take to process all of the pictures?
A: Each picture will take 2 minutes to process. 2 x 960 = 1,920 minutes. There are 60 minutes in an hour. To find the hours, divide the minutes by 60. 1,920 / 60 = 32 hours. The answer is 32.
Question: Barney the dinosaur weighs 1500 pounds more than five regular dinosaurs combined. If each regular dinosaur weighs 800 pounds, find the combined weight of Barney and the five regular dinosaurs' weights?
Answer: If each regular dinosaur weighs 800 pounds, five regular dinosaurs weigh 5 * 800 = 4000 pounds. Since Barney the dinosaur weighs 1500 pounds more than five regular dinosaurs combined, he weighs 4000 + 1500 = 5500 pounds. The combined weight of Barney and the five regular dinosaurs' weights is 5500 + 4000 = 9500 pounds. The answer is 9500.
