Question: In preparation for the upcoming Olympics, Rita's swimming coach requires her to swim a total of 1,500 hours. Rita has already completed 50 hours of backstroke, 9 hours of breaststroke, and 121 hours of butterfly, but she is unhappy with her inconsistency. She has therefore decided to dedicate 220 hours every month practicing freestyle and sidestroke. How many months does Rita have to fulfill her coach’s requirements?
Answer: Step-by-step reasoning process: So far, time spent practicing backstroke, breaststroke, and butterfly is 50 + 9 + 121 = 180 hours. Since Rita’s must swim 1500 hours, the freestyle and sidestroke practice sessions will take 1500 - 180 = 1320 hours. Rita will practice for 220 hours / month, meaning she will meet her coach’s target in 1320 / 220 = 6 months.
So the answer is 6.

Question: Dylan's mother is throwing a baby shower for her best friend. She is expecting 40 guests, of whom she has cleared the parking lot to park in to, leaving only her car and her husband's jeep in the parking lot. The 40 guests, though, arrive in only 10 cars that they park in the parking lot. If each car has 4 wheels, how many car wheels are there in the parking lot, including both of Dylan's parent's car wheels?
Answer: Step-by-step reasoning process: 10 cars are parked around for the party, 10 x 4 wheels each car = 40 wheels total. Dylan's parents both have a car with 4 wheels each, 2 x 4 = 8 more wheels. Combined, there are 40 + 8 = 48 wheels total on the Dylan family property.
So the answer is 48.

Question: Paul makes pencils, making 100 pencils a day five days a week. He started the week with 80 pencils in his stock, and during the week he sold 350 pencils. How many pencils did he have in his stock at the end of the week?
Answer: Step-by-step reasoning process: Making 100 pencils a day, he made 100 pencils / day * 5 days / week = 500 pencils during the week. With the pencils from the stock, he got 500 pencils + 80 pencils = 580 pencils. Subtracting the ones he sold, he has 580 pencils - 350 pencils = 230 pencils.
So the answer is 230.

Question: A box of six popsicles was left out in the sun and is slowly melting. Every time a popsicle melts the remaining popsicles melt twice as fast as the previous one. How many times faster than the first popsicle does the last popsicle’s remains melt?
Answer:
Step-by-step reasoning process: The remains of the second popsicle melt 2 * 1 = 2 times as fast as the first. The remains of the third popsicle melt 2 * 2 = 4 times as fast as the first. The remains of the fourth popsicle melt 2 * 4 = 8 times as fast as the first. The remains of the fifth popsicle melt 2 * 8 = 16 times as fast as the first. The remains of the sixth popsicle melt 2 * 16 = 32 times as fast as the first popsicle.
So the answer is 32.
