Question
A professional photographer is hired to take individual photos of each of the 240 graduatingstudents. If the photographer can take photos of 6 students in 30 minutes, how many hourswill the photographer need to take photos of all the students
Solution 1
Step 1: Determine how many students the photographer can photograph in one hour. Since there are 60 minutes in an hour and the photographer can photograph 6 students in 30 minutes, the photographer can photograph 12 students in one hour (6 students x 2).
Step 2: Determine how many hours it will take the photographer to photograph all 240 students. Divide the total number of students by the number of students the photographer can photograph in one hour. So, 240 students ÷ 12 students/hour = 20 hours.
Therefore, it will take the photographer 20 hours to photograph all 240 students.
Solution 2
First, we need to determine how many students the photographer can photograph in one hour. Since there are 60 minutes in an hour and the photographer can photograph 6 students in 30 minutes, the photographer can photograph 12 students in one hour (6 students per 30 minutes * 2).
Next, we need to determine how many hours it will take for the photographer to photograph all 240 students. To do this, we divide the total number of students by the number of students the photographer can photograph in one hour.
So, 240 students / 12 students per hour = 20 hours.
Therefore, it will take the photographer 20 hours to photograph all 240 students.
