Question: Can you explain how to solve this math problem: Emily can peel 6 shrimp a minute and saute 30 shrimp in 10 minutes. How long will it take her to peel and cook 90 shrimp?
Answer: 
First find how long it takes Emily to peel the shrimp: 90 shrimp / 6 shrimp/minute = 15 minutes
Then find how many batches of shrimp she needs to cook: 90 shrimp / 30 shrimp/batch = 3 batches
Then multiply the number of batches by the time per batch to find the total cook time: 3 batches * 10 minutes/batch = 30 minutes
Then add the peeling time to find the total time Emily spends: 30 minutes + 15 minutes = 45 minutes
