What is the total time required to complete the film developing process given the step times: Developer 2 1/4 minutes, Rinse 3/4 minute, Fix solution 3 1/2 minutes, Final wash 19 minutes?

• A. 24 1/4 minutes
• B. 25 minutes
• C. 25 3/4 minutes
• D. 25 1/2 minutes

Answer: (D)

When calculating total time, add each step’s duration together. Start with the first two steps: 2 1/4 minutes plus 3/4 minute equals 3 minutes (since 1/4 + 3/4 = 1). Then add the fix time of 3 1/2 minutes to reach 6 1/2 minutes. Finally, add the final wash of 19 minutes to get 25 1/2 minutes. So the total development time is 25 1/2 minutes.
