Answer:
Let's break it down: Emil can wash the dishes in 45 minutes alone, and he has already been washing for 15 minutes before Anne arrived. So, he has 30 more minutes of work left. Anne can wash the same amount of dishes in 30 minutes. Together, their combined rate is 1/30 + 1/45 = 5/90 + 3/90 = 8/90 = 4/45 dishes per minute. To finish the remaining 30 minutes of work, it would take them 30 / (4/45) = 337.5 minutes. Since Anne arrived after Emil had been washing for 15 minutes, the total time it takes them to finish washing the dishes since she arrived would be 337.5 + 15 = 352.5 minutes.
