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? Let's be accurate as possible.
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: 32.
