[Question]Jack bought an ice cream cone before jogging to the beach. If the ice cream cone will melt in 10 minutes, the beach is 16 blocks away, and each block is 1/8th of a mile, how fast does Jack need to jog (in miles per hour) to get to the beach before the ice cream melts?
[Answer]First find the total distance to the beach: 16 blocks * 1 / 8 mile / block = 2 miles. Then find how long in hours Jack has to get to the beach: 10 minutes / 60 minutes / hour = 1 / 6 hour. Then divide the distance Jack needs to cover by the time in hours he has to find how fast he needs to jog: 2 miles / 1 / 6 hour = 12 miles / hour. The answer is 12.

Question: Willow’s daughter had a slumber party with 3 of her friends. For breakfast, they wanted pancakes. Willow’s pancake recipe makes 1 serving of 4 pancakes. Each of the girls wanted a serving and a half of pancakes. Willow’s son wanted 3 servings of pancakes. How many single pancakes will Willow make for the girls and her son?
Answer:
The daughter and her 3 friends each want 1.5 servings of pancakes so that’s 4 * 1.5 = 6 servings of pancakes. Willow’s son wants 3 servings of pancakes and the girls want 6 so that’s 3 + 6 = 9 servings of pancakes. Each serving makes 4 pancakes and Willow needs to make 9 servings for a total of 4 * 9 = 36 pancakes. The answer is 36.
