Scenario: If Aarti and Rita can do a job in 7 minutes (working together at their respective constant rates) and Aarti can do the job alone in 11 minutes and 40 seconds. In how many hours can Rito do the job alone? (Note: Time must be measured in minutes and ONLY the FINAL ANSWER must be measured in minutes and rounded off to its nearest whole number.) A. Write the equation (3pts) B. Using your equation in letter a, solve and show your solution (5pts) C. Interpret your final answer \& Explain how you get your final answer (2pts)
