[Question]A club with 30 members ordered fruit juices. Two-fifths of them ordered lemon juice. One-third of the remaining members ordered mango juice, and the rest ordered orange juice. How many members ordered orange juice?
[Answer]30 x 2 / 5 = 12 members ordered lemon juice. So, 30 - 12 = 18 members did not order lemon juice. Since 1 / 3 of the remaining ordered mango juice, then 18 x 2 / 3 = 12 members ordered mango juice. Therefore, 18 - 12 = 6 members ordered orange juice. The answer is 6.
Q: Daniel owns a textile company. Every Monday he delivers 20 yards of fabric, and every Tuesday he delivers twice the amount of fabric he delivers on Monday. Every Wednesday, he delivers 1/4 of the amount of fabric he delivers on Tuesday. If each yard of fabric costs $2 and each yard of yarn costs $3, how much does he earn from Monday to Wednesday?
A: Every Tuesday, Daniel delivers 20 x 2 = 40 yards of fabric. Every Wednesday, he delivers 40 x 1 / 4 = 10 yards of fabric. Thus, he delivers a total of 20 + 40 + 10 = 70 yards of fabric from Monday to Wednesday. Therefore, Daniel earns $2 x 70 = $140 from it. The answer is 140.
Question: The teacher brings in 14 mini-cupcakes and 12 donut holes for the class. There are 13 students in the class. If each student gets the exact same amount, how many desserts does each student get?

[Question]Eden, Mary and Iris gather sand to fill their sandbox. Eden carried 4 buckets of sand. Mary carried 3 more buckets of sand than Eden. Iris carried 1 less bucket of sand than Mary. If each bucket contains 2 pounds of sand, how many pounds of sand did they collect in total?
[Answer]Mary carried 4 + 3 = 7 buckets of sand. Iris carried 7 – 1 = 6 buckets of sand. All together, they carried 4 + 7 + 6 = 17 buckets of sand. The sand weighed a total of 17 * 2 = 34 pounds. The answer is 34.

Question: Theon's ship can move 15 nautical miles per hour while Yara's ship can move 30 nautical miles per hour. If their destination is 90 nautical miles away, how many hours ahead will Yara be ahead of Theon?
