Question: The chocolate factory produces 50 candies per hour. It has to fulfill an order and produce 4000 candies. How many days will it take to complete the order if the factory works for 10 hours every day?
Answer: Step-by-step reasoning process: It will take 4000 candies / 50 candies / hour = 80 hours to make all the candy. It will take 80 hours / 10 hours / day = 8 days to complete the order.
So the answer is 8.

Question: Elsa gets 500 MB of cell phone data each month. If she spends 300 MB watching Youtube and 2/5 of what's left on Facebook, how many MB of data does she have left?
Answer: Step-by-step reasoning process: First subtract the 300 MB Elsa spent on YouTube: 500 MB - 300 MB = 200 MB. Then multiply 200 MB by 2 / 5th to find out how much data Elsa spent on Facebook: 200 MB * 2 / 5 = 80 MB. Finally, subtract the data Elsa spent on Facebook from the 200 MB: 200 MB - 80 MB = 120 MB.
So the answer is 120.

Question: Tom weighs 150 kg. He manages to hold 1.5 times his weight in each hand while wearing a weight vest weighing half his weight. How much total weight was he moving with?
Answer: Step-by-step reasoning process: He was carrying 150 * 1.5 = 225 kg in each hand. So he had 225 * 2 = 450 kg in his hands. The weight vest weighed 150 * .5 = 75 kg. So he had a total of 450 + 75 = 525 kg he was moving.
So the answer is 525.

Question: Yolanda leaves home for work at 7:00 AM, riding her bike at 20 miles per hour. 15 minutes after she leaves, her husband realizes that she forgot her lunch, and jumps in the car to bring it to her. If he drives at 40 miles per hour and follows the exact same route as Yolanda, how many minutes will it take him to catch her?
Answer:
Step-by-step reasoning process: Let x be the number of minutes it takes Yolanda's husband to catch her. We know that Yolanda will spend a total of x + 15 minutes riding her bike since she left 15 minutes before her husband. The distance each person travels is equal to their travel speed times the number of minutes they spend traveling. That means Yolanda's distance is equal to 20 mph * (x + 15) and her husband's distance is equal to 40 mph * x. Yolanda's husband catches up to her when they've both traveled the same distance, which is when 20(x + 15) = 40x. We can simplify this equation by multiplying 20 through the parentheses to get 20x + 300 = 40x. Then we can subtract 20x from each side to get 300 = 20x. Finally, we divide both sides by 20 to find that x = 15.
So the answer is 15.
