[Question]The Zargon Destroyer spacecraft can travel at 2 billion miles per hour in normal space, but when moving through a black hole they travel three times faster. If the Zargon Destroyer is making a voyage that travels seven hours in normal space and two hours through a black hole, how many billions of miles would they have traveled?
[Answer]A spacecraft flying through normal space for seven hours at 2 - billion miles per hour travels 7 * 2 = 14 billion miles. A spacecraft flying through a black hole at 3 * 2 = 6 billion miles per hour. Thus, a spacecraft flying through a black hole for two hours travels 2 * 6 = 12 billion miles. Therefore, in total, the Zargon spacecraft will travel 14 + 12 = 26 billion miles. The answer is 26.
Q: In 5 years, Nacho will be three times older than Divya. If Divya is currently 5 years old, what's the sum of their ages now?
A: If Divya is currently 5 years old, she will be 5 + 5 = 10 years old in five years. Since in 5 years Nacho will be three times older than Divya, he will be 3 * 10 = 30 years older than Divya. Nacho's total age in five years will be 30 + 10 = 40 years. Currently, Nacho is 40 - 5 = 35 years old. The sum of Divya and Nacho's age now is 35 + 5 = 40 years. The answer is 40.
Question: The cheerleading coach is ordering new uniforms. There are 4 cheerleaders who need a size 2, a certain number who need a size 6, and half that number who need a size 12. If there are 19 cheerleaders total, how many cheerleaders need a size 6?
Answer: Let s be the number of cheerleaders who need a size 6 and t be the number who need a size 12. We know that s = 2t and s + t + 4 = 19. Substituting the first equation into the second equation, we get 2t + t + 4 = 19. Combining like terms, we get 3t + 4 = 19. Subtracting 4 from both sides, we get 3t = 15. Dividing both sides by 3, we get t = 5. Substituting that value back into the equation s = 2t, we get s = 2 * 5 = 10. The answer is 10.
[Question]Joseph gave 23 cards to each of his 15 students and had 12 cards left. How many cards did Joseph have at first?
[Answer]He gave 23 cards each to 15 students for a total of 23 * 15 = 345 cards. He has 12 cards left, so originally the number of cards was 345 + 12 = 357 cards. The answer is 357.
Q: There are 50 oysters on the rocks at La Push Park and 72 crabs by the beach. Eric, who loves walking by the beach, makes a note of this and goes home. The next day, he realizes only half the number of Oysters were on the rocks, and only 2/3 the number of crabs as the previous day are on the beach. How many oysters and crabs did he count in total in the two days?
A: The first day he saw 50 oysters + 72 crabs = 122 animals. On the second day, he saw 1 / 2 * 50 oysters = 25 oysters. The number of crabs by the beach on the second day was 2 / 3 * 72 crabs = 48. He saw 48 crabs + 25 oysters = 73 animals on the second day. The total for the two days is 73 animals + 122 animals = 195 animals. The answer is 195.
Question: Olaf is playing a game with his dad. He scored three times more points than his dad, who scored 7 points. How many points did they score in total?
