The total of minutes the treatment will take is 2 hours x 60 minutes / hour = 120 minutes. After 120 minutes has passed the total amount of drops that the patient will receive is 20 drops / minute x 120 minutes = 2400 drops. Knowing the number of drops, we know that the patient has taken 2400 drops x 5 ml / 100 drops = 120 ml.
The answer: 120
Reverse engineering the question: A patient is receiving treatment through a saline drip which makes 20 drops per minute. If the treatment lasts 2 hours, and every 100 drops equal 5 ml of liquid, how many milliliters of treatment will the patient receive after the 2 hours have passed?
Reasoning and answer: First find how many degrees the temperature of the water needs to increase: 212 degrees - 41 degrees = 171 degrees. Then divide that amount by the number of degrees the water temperature increases each minute to find how long it takes the water to boil: 171 degrees / 3 degrees / minute = 57 minutes. Now figure out how long it takes to mix the pasta and make salad by dividing the pasta cook time by 3: 12 minutes / 3 = 4 minutes. Now add the boiling time, cook time, and mixing time to find the total time it takes to make dinner: 57 minutes + 4 minutes + 12 minutes = 73 minutes.
The answer: 73

Question: Jason is making pasta. He fills the pot with 41 degree water. Each minute the temperature of the water increases by 3 degrees. Once the water reaches 212 degrees and is boiling, Jason needs to cook his pasta for 12 minutes. Then it will take him 1/3 that long to mix the pasta with the sauce and make a salad. How many minutes does it take Jason to cook dinner?
He gave 3 / 3 = 1 box away. So he has 3 - 1 = 2 boxes. So he got 2 * 20 = 40 burritos. He ate 3 * 10 = 30 burritos. So he has 40 - 30 = 10 burritos left.
The answer: 10
Reverse engineering the question: John buys 3 boxes of burritos. He gives away a 3rd of them to his friend. Each box has 20 burritos. He eats 3 burritos per day for 10 days. How many burritos does he have left?
Reasoning and answer: 7 days a week Laura drives 20 miles to school, so Laura drives 7 x 20 = 140 miles to school in one week. The supermarket is 10 miles farther away than the school. Therefore the supermarket is 10 + 10 = 20 miles away from Laura's house. Laura drives 20 miles each way to and from the supermarket. Each trip is 20 x 2 = 40 miles. Laura drives 40 miles twice a week to visit the supermarket. Therefore she drives 40 x 2 = 80 miles in total a week to and from the supermarket. In total Laura drives 140 + 80 = 220 miles each week.
The answer: 220

Question: Laura's House is a 20-mile round trip from her school. The supermarket is 10 miles farther away from the school. If Laura drives to school every morning and two afternoons a week drives to the supermarket. How many miles does Laura driver per week?
First, find how many leaves the roof can hold: 500 pounds * 1000 leaves / pound = 500000 leaves. Then divide that by the number of leaves that fall each day to find how many days before the roof collapses: 500000 leaves / 100 leaves / day = 5000 days.
The answer: 5000
Reverse engineering the question: Bill's roof can bear 500 pounds of weight. If 100 leaves fall on his roof every day, and 1000 leaves weighs 1 pound, how many days will it take for his roof to collapse?
If x is Maria's age, then Mario's age is x + 1. The equation that represents the sum of their ages is x + x + 1 = 7. By combining like terms, the equation becomes 2x = 6. Hence, the value of x which represents the age of Maria is 6 / 2 = 3. So Mariu is 3 + 1 = 4 years old.
The answer: 4
Reverse engineering the question:
The sum of Mario and Maria's ages now is 7. Mario is 1 year older than Maria. How old is Mario?
