Question: A doctor needs to give medicine to a child, and he knows that he cannot give the same amount of medicine that he would give to an adult. The instructions say that for every kilogram of weight the child must be given 5 ml of medicine. The doctor knows that the child weighs 30 kilograms and that also the full dose has to be given in 3 equal parts. How many milligrams will each part of the dose be?
Answer: The total number of ml needed is 30 kg x 5 ml / kg = 150 ml. Each dose has to be 150 ml / 3 doses = 50 ml / dose. The answer is 50.
[Question]Blanch has 15 slices of pizza in the fridge. During breakfast, she eats 4 slices. At lunch, Blanch eats 2 slices, then takes two slices as a snack. Finally, she consumes 5 slices for dinner. How many slices of pizza are left?
[Answer]During breakfast, Blanch has 15 - 4 = 11 slices left. At lunch, she still has 11 - 2 = 9 slices left. After the snack, there are still 9 - 2 = 7 slices left. Finally after dinner, Blanch has 7 - 5 = 2 slices left. The answer is 2.
Q: If Amanda can run the length of a football field 2000 meters in length in 2 hours, how long would it take her to run the length of a 10000-meter track at the same speed?
A: Running the length of a football field 2000 meters in 2 hours is a speed of 2000 / 2 = 1000 meters per hour. At the same speed, Amanda will run the length of a 10000 - meter track in 10000 / 1000 = 10 hours. The answer is 10.
Question: Scott wants to make and freeze a large batch of ratatouille. At the farmers' market he buys 5 pounds of eggplants and 4 pounds of zucchini at $2.00 a pound. He needs 4 pounds of tomatoes that are $3.50 a pound. The onions are $1.00 a pound and he needs 3 pounds. Then he needs a pound of basil which is sold for $2.50 per half pound. If this yields 4 quarts, how much does each quart cost?
Answer: He buys 5 pounds of eggplants and 4 pounds of zucchini so he buys 5 + 4 = 9 pounds of produce. These 9 pounds are $2.00 a pound for a total of 9 * 2 = $18.00. He needs 4 pounds of tomatoes that are $3.50 a pound for a total of 4 * 3.50 = $14.00. He needs 3 pounds of onions that are $1.00 a pound so that's 3 * 1 = $3.00. The basil is sold by the half - pound and he needs a full pound so that's 2.50 * 2 = $5.00. The eggplants and zucchinis cost $18.00, the tomatoes are $14.00, the onions are $3.00 and the basil is $5.00 for a total of 18 + 14 + 3 + 5 = $40.00. This recipe makes 4 quarts and the total price of the vegetables was $40.00 so each quart costs 40 / 4 = $10.00. The answer is 10.
[Question]Jane runs 3 kilometers in two hours. What is her speed in meters per minute?
[Answer]Since 1 kilometer is equal to 1000 meters, then 3 kilometers is 3 x 1000 = 3000 meters. Since an hour has 60 minutes, then 2 hours is equal to 2 x 60 = 120 minutes. Therefore, her speed is 3000 meters / 120 hours = 25 meters per minute. The answer is 25.
[Question]Jake and Penny are hunting snakes. Jake's snake is 12 inches longer than Jenny's snake. If the two snakes have a combined length of 70 inches, how long is Jake's snake?
[Answer]
Let j be the length of Jake's snake and p be length of Penny's snake. We know that j + p = 70, and j = p + 12. We can substitute the second equation into the first equation to get p + 12 + p = 70. Combining like terms, we get 2p + 12 = 70. Subtracting 12 from both sides, we get 2p = 58. Dividing both sides by 2, we get p = 58 / 2 = 29 inches. Penny's snake is 29 inches. Substituting that length in to the equation j = p + 12, we get j = 29 inches + 12 inches = 41 inches. The answer is 41.
