[Question]Two-thirds of all the animals on my street are cats and the rest are dogs. If there are 300 animals on the street, what's the total number of legs of dogs that are on the street?
[Answer]The number of cats on the street is 2 / 3 * 300 = 200. If there are 300 animals on the street, and 200 are cats, there are 300 - 200 = 100 dogs. Since a dog has four legs, the total number of legs the 100 dogs have is 100 * 4 = 400 legs. The answer is 400.

Question: Emery's family decides to travel for a weekend trip. They drive the first 100 miles in 1 hour. They stop at a McDonald's and then continue the rest of the journey for 300 miles. What's the total number of hours they traveled?
Answer: If the first 100 miles took one hour, then let's say the next 300 miles took x hours. if 100 miles = 1 hour, then 300 miles = x. To find the number of hours traveled for the 300 miles, x = 300 * 1 / 100. x = 3 hours. The total number of hours will be 3 + 1 = 4 hours. The answer is 4.
