Q: Cindy can run at 3 miles per hour and walk at 1 mile per hour. If she runs for half a mile and then walks for half a mile, how many minutes will it take her to travel the full mile?
A: It will take her 0.5 miles / 3 mph * (60 minutes / 1 hour) = 10 minutes to run half a mile. It will take her 0.5 miles / 1 mph * (60 minutes / 1 hour) = 30 minutes to walk half a mile. Her total time is 10 + 30 = 40 minutes. The answer is 40.
Question: A teacher asked Adelaide, Ephraim, and Kolton to buy ducks and monitor their growth patterns and features for their science class. Adelaide bought twice the number of ducks that Ephraim bought, while Ephraim bought 45 fewer ducks than Kolton. If Adelaide bought 30 ducks, what's the average number of ducks the three bought?
Answer: If Adelaide bought 30 ducks, Ephraim bought 30 ducks / 2 = 15 ducks. Since Ephraim bought 45 fewer ducks than Kolton, Kolton bought 45 ducks + 15 ducks = 60 ducks. The total number of ducks the three bought is 60 ducks + 15 ducks + 30 ducks = 105 ducks. The average number of ducks each bought is 105 ducks / 3 people = 35 ducks / person. The answer is 35.

Question: A pastry chef is making brownies but is running out of butter. The recipe he is following calls for 2 ounces of butter for every 1 cup of baking mix; however, it allows 2 ounces of coconut oil to be substituted for the 2 ounces of butter if necessary. The chef would like to use as much butter as possible before switching over and substituting coconut oil. If the chef had 4 ounces of butter remaining, and he plans on using 6 cups of baking mix, how many ounces of coconut oil will he end up using?
Answer: Every 2 ounces of butter is enough to cover 1 cup of baking mix, so the chef's remaining 4 ounces of butter will be enough to cover 4 / 2 = 2 cups of baking mix. This leaves 6 - 2 = 4 cups of baking mix that will require the use of coconut oil as a substitute. Since each cup of baking mix requires 2 ounces of coconut oil, these 4 cups will require a total of 4 * 2 = 8 ounces of coconut oil. The answer is 8.
Q: Jillian, Savannah, and Clayton were collecting shells on the beach. Jillian collected 29, Savannah collected 17, and Clayton collected 8. They decided that they wanted to give the shells to two of their friends who had just arrived. They put their shells together and distributed them evenly to each friend. How many shells did each friend get?
A:
The kids collected 29 + 17 + 8 = 54 shells. If they distribute the shells evenly between 2 friends, 54 / 2 = 27 shells for each friend. The answer is 27.
