Q: Nurse Missy is attending to the needs of 12 patients in her hospital ward. Most of her patients require standard care, but one-third of her patients have special dietary requirements, which increases the serving time by 20%. At dinner time, she brings each patient their meal. It takes 5 minutes to serve each standard care patient. How long does it take, in minutes, for Missy to serve dinner to all of her patients?
A: Nurse Missy has 12 * (1 / 3) = 4 special needs patients. She has 12 - 4 = 8 standard care patients. Special needs patients take 20% longer to serve, which means serving takes 1.2 * 5 = 6 minutes per patient. To serve dinner to all of her standard care patients, it will take 5 * 8 = 40 minutes. To serve dinner to all of her special needs patients, it will take 6 * 4 = 24 minutes. In total, it will take 40 + 24 = 64 minutes to serve dinner to all of her patients. The answer is 64.
Question: The ratio representing the age of Halima, Beckham, and Michelle is 4:3:7, respectively. If the total age for the three siblings is 126, calculate the age difference between Halima and Beckham.
Answer: The total ratio representing the age of the three siblings is 4 + 3 + 7 = 14. Halima's age is represented by the fraction 4 / 14, which means she is 4 / 14 * 126 = 36 years old. Beckhams age, from the total age of the three, is 3 / 14 * 126 = 27. The difference in age between Halima and Beckham is 36 - 27 = 9. The answer is 9.

Q: Michael wants to dig a hole 400 feet less deep than twice the depth of the hole that his father dug. The father dug a hole at a rate of 4 feet per hour. If the father took 400 hours to dig his hole, how many hours will it take for Michael to dig a hole that is 400 feet less than twice as deep as his father's hole working at the same rate?
A: Since the father dug a hole with a rate of 4 feet per hour, if the father took 400 hours digging the hole, he dug a hole 4 * 400 = 1600 feet deep. Twice the depth of the hole that Michael's father dug is 2 * 1600 = 3200 feet. Michael wants to dig a hole 400 feet less than twice the depth of the hole that his father dug, meaning he wants to dig a hole 3200 - 400 = 2800 feet deep. To dig a hole that is 400 feet less than twice as deep as his father's hole working at a rate of 4 feet per hour, Michael will have to work for 2800 / 4 = 700 hours. The answer is 700.
Question: Sam spends sixty minutes studying Science, eighty minutes in Math, and forty minutes in Literature. How many hours does Sam spend studying the three subjects?
