Question: When you take Hiram's age and then add 12, you get 4 less than twice Allyson's age. If Hiram is 40 years old, how old is Allyson?
Answer: Step-by-step reasoning process: If Hiram's age is 40, when you add 12, his age becomes 40 + 12 = 52. If you add 4 from Hiram's age after adding twelve to his age, you get 52 + 4 = 56, which is twice Allyson's age. Allyson's age is 56 / 2 = 28 years.
So the answer is 28.

Question: Five percent of the 300 senior students got a full merit college scholarship and ten percent of them got a half merit scholarship. How many senior students did not get any scholarships?
Answer: Step-by-step reasoning process: 300 x 5 / 100 = 15 senior students got a full merit scholarship. 300 x 10 / 100 = 30 senior students got a half merit scholarship. So, a total of 15 + 30 = 45 students got scholarships. Therefore, 300 - 45 = 255 senior students did not get any scholarships.
So the answer is 255.

Question: Mary and Jimmy start running from the same spot, but in opposite directions. Mary runs at 5 miles per hour and Jimmy runs at 4 miles per hour. What is the distance between them after 1 hour?
Answer:
Step-by-step reasoning process: In 1 hour, Mary will have traveled 5 miles / hour * 1 hour = 5 miles. In 1 hour, Jimmy will have traveled 4 miles / hour * 1 hour = 4 miles. Since they are running in opposite directions, the distance between them will be 5 miles + 4 miles = 9 miles.
So the answer is 9.
