[Question]5 years ago, a mother was twice as old as her daughter. If the mother is 41 years old now, how old will the daughter be in 3 years?
[Answer]The mother is 41 years old now, so 5 years ago she was 41 - 5 = 36 years old. At that time the daughter's age was half hers so the daughter was 36 / 2 = 18 years old. Now (5 years after that time) the daughter is 18 + 5 = 23 years old. In 3 years, the daughter will be 23 + 3 = 26 years old. The answer is 26.
Q: Ellen is painting flowers on a vase. It takes her 5 minutes to paint a lily, 7 minutes to paint a rose, 3 minutes to paint an orchid, and 2 minutes to paint a vine. How long will it take her to paint 17 lilies, 10 roses, 6 orchids and 20 vines?
A: First find the total time Ellen spends painting lilies: 5 minutes / lily * 17 lilies = 85 minutes. Then find the total time Ellen spends painting roses: 7 minutes / lily * 10 roses = 70 minutes. Then find the total time Ellen spends painting orchids: 3 minutes / orchid * 6 orchids = 18 minutes. Then find the total time Ellen spends painting vines: 2 minutes / lily * 20 vines = 40 minutes. Then add the amount of time Ellen spends on each type of flower to find the total time: 85 minutes + 70 minutes + 18 minutes + 40 minutes = 213 minutes. The answer is 213.

Q: Lena is making a collage with pictures of all her closest friends and newspaper clippings that are about their interests. She has found three clippings for each friend’s pictures. It takes her six drops of glue to stick down each clipping. Lena has already glued her seven closest friends’ pictures. How many drops of glue will she need for the newspaper clippings for her collage?
A: Lena has 3 clippings per friend, so she has 3 * 7 = 21 clippings to glue. She needs 6 drops of glue per clipping, so she will need 6 * 21 = 126 drops of glue. The answer is 126.
Question: A volcano erupts and spews ash into the sky. The ash cloud spreads out in a diameter eighteen times as far as the distance it shot up into the sky. If the ashes erupted three hundred feet into the sky, what was the radius of the ash cloud in feet?
Answer:
The ash cloud spread out 300 * 18 = 5400 feet in diameter. The radius is half the diameter, so the ash cloud had a radius of 5400 / 2 = 2700 feet. The answer is 2700.
