At his first speed, Kevin ran 10 miles per hour * 0.5 hours = 5 miles. At his second speed, he ran 20 miles per hour * 0.5 hours = 10 miles. 15 minutes is a quarter of an hour so at his third speed, he ran 8 miles per hour * 0.25 hours = 2 miles. Therefore, Kevin ran a total of 5 miles + 10 miles + 2 miles = 17 miles.
The answer: 17
Reverse engineering the question: Kevin has been for a run and wants to calculate how far he traveled. He ran at 10 miles per hour for half an hour, 20 miles per hour for half an hour, then ran at 8 miles per hour for 15 minutes. How many miles has Kevin run?


Reasoning and answer: The buffet cost for Mr. Smith and his wife is $30 x 2 = $60. The buffet cost for his children is $15 x 3 = $45. The buffet cost for 1 senior citizen is $30 x 90% = $27. B. uffet cost for the grandparents is $27 x 2 = $54. Buffet cost for the entire family is $60 + $45 + $54 = $159.
The answer: 159

Question: Mr. Smith takes his wife, his parents, and his 3 children to a seafood buffet. The price for the adult buffet is $30. The price for the children’s buffet is $15. Senior citizens get a 10% discount. How much does Mr. Smith spend on the buffet for his entire family?


The total time taken for the whole journey is 9:00 - 6:00 = 3 hours. The total time taken in minutes is 3 * 60 = 180 minutes. If it takes 40 minutes to reach the first station, then the rest of the journey takes 180 - 40 = 140 minutes.
The answer: 140
Reverse engineering the question: Mr. Langsley commutes to work every day by bus. The bus picks him up at 6:00 a.m. and takes forty minutes to arrive at the first station. If Mr. Langsley arrives at work at 9:00 a.m., what's the total time taken in minutes from the first station to Mr. Langsley's workplace?


Reasoning and answer: If Mr. Jones has 6 shirts for every pair of pants, and he has 40 pants, the total number of shirts he has is 6 * 40 = 240. The total number of pieces of clothes he owns is 240 + 40 = 280.
The answer: 280

Question: If Mr. Jones has 6 shirts for every pair of pants, and he has 40 pants, what's the total number of pieces of clothes he owns if all other factors remain the same?


Camilla needs 12 / 3 = 4 batches of pizza dough. 4 batches of pizza would require 30 x 4 = 120 minutes. Camilla needs to bake the pizzas 12 / 2 = 6 times. 6 times in the oven would take 30 x 6 = 180 minutes. Altogether, it would take 120 + 180 = 300 minutes to finish making 12 pizzas. 300 minutes is 300 / 60 = 5 hours.
The answer: 5
Reverse engineering the question: It takes 30 minutes to make pizza dough and another 30 minutes in the oven for the pizza to cook. If one batch of pizza dough can make 3 pizzas but the oven can only fit 2 pizzas at a time, how many hours would it take for Camilla to finish making 12 pizzas?


1 / 6 * 240 students = 40 students. So 40 students read three or more novels. 35 / 100 * 240 students = 84 students. So 84 students read two novels. 5 / 12 * 240 students = 100 students. So 100 students read a novel. 240 students – (40 students + 84 students + 100 students) = 240 students – 224 students = 16 students. So 16 students don't read novels.
The answer: 16
Reverse engineering the question:
240 sixth-grade students were asked about the number of novels they read per month. 1/6 of students read three or more novels, 35% of students read two novels, 5/12 of students read one novel, and the rest of the students do not read anything. Calculate the number of students who do not read novels.
