[Question]It takes Emmalyn and her research team, the Polar Bears, 30 minutes to fully navigate around a volcanic island. On Saturday, they decided to start off by rounding the island once. They then re-grouped and planned out the rest of their weekend research schedule. They completed 10 more round that day and then went home. When they came on Sunday, they were able to complete 15 rounds. Calculate the total time, in minutes, the Polar Bears spent circling the island over that weekend.
[Answer]On the first day, they started off doing one round of 30 minutes. The team did ten more rounds on day one which took 10 * 30 = 300 minutes. The total time they took circumnavigating the land on the first day is 300 + 30 = 330 minutes. On the second day, they did 15 rounds, which took 30 minutes each, giving 15 * 30 = 450 minutes. The total number of rounds took 330 + 450 = 780 minutes. The answer is 780.
Q: James has five huskies, two pitbulls and four golden retrievers, all female. They became pregnant and each golden retriever had two more pups than each husky. If the huskies and pitbulls had 3 pups each, How many more pups than adult dogs are there in total?
A: There are 5 + 2 = 7 huskies and pitbulls. 7 huskies and pitbulls had 3 pups each for a total of 3 * 7 = 21 pups. Each golden retriever had 2 more pups each than the huskies who had 3 each so each golden retriever had 3 + 2 = 5 pups. 4 golden retrievers had 5 pups each for a total of 20 pups. There are a total of 21 + 20 = 41 pups. There are a total of 5 + 2 + 4 = 11 adult dogs. There are 41 - 11 = 30 more pups than adult dogs. The answer is 30.
