[Question]The sum of the ages of Jeremy, Sebastian and Sophia in three years is 150. Currently, Sebastian is 4 years older than Jeremy. If Jeremy's age is 40, calculate Sophia's age three years from now?
[Answer]The age of Jeremy three years from now will be 40 + 3 = 43 years. Since Sebastian age is four years more than Jeremy's, Sebastian is currently 40 + 4 = 44 years. In three years, Sebastian will be 44 + 3 = 47 years old. The total age of Jeremy and Sebastian in three years will be 47 + 43 = 90. If the total age of Jeremy, Sebastian and Sophia in three years is 150, then Sophia's age in three years will be 150 - 90 = 60. The answer is 60.
Q: A snake's head is one-tenth its length. If a snake is 10 feet long, calculate the length of the rest of its body minus the head.
A: A snake's head is one - tenth its length, which is 1 / 10 * 10 = 1 foot. Since the snake's head is 1 foot, the rest of its body is 10 - 1 = 9 feet long. The answer is 9.
Question: Jane runs 3 kilometers in two hours. What is her speed in meters per minute?
Answer: Since 1 kilometer is equal to 1000 meters, then 3 kilometers is 3 x 1000 = 3000 meters. Since an hour has 60 minutes, then 2 hours is equal to 2 x 60 = 120 minutes. Therefore, her speed is 3000 meters / 120 hours = 25 meters per minute. The answer is 25.
[Question]The price of a math textbook in the school bookshop is $45. If those sold in bookshops outside the school cost 20% less, how much can Peter save by buying from other bookshops rather than the school's if he wants to buy 3 math textbooks?
[Answer]20% of $45 is (20 / 100) * $45 = $9. The price of the textbook in other bookshops cost $9 less than $45 which is $45 - $9 = $36. Three textbooks from the school bookshop would cost $45 * 3 = $135. Three textbooks from another bookshop would cost $36 * 3 = $108. Peter can save $135 - $108 = $27 by buying from another bookshop. The answer is 27.
Q: Mandy is 3 years old. Her brother is 4 times as old as she is. Her sister is 5 years younger than her brother. What is the age difference between Mandy and her sister?
