Question and rationale: The question is: From his apartment, Kona drives 9 miles to the bakery. From there, he drives 24 miles to his grandmother’s house. From her house, he drives 27 miles straight to his apartment. How many additional miles did Kona drive round trip to the bakery stop, compared to a round trip without the bakery stop?
Step-by-step reasoning process: With the bakery stop, Kona drove a total of 9 + 24 + 27 = 60 miles. Without the bakery stop, Kona drove a total of 27 + 27 = 54 miles. With the bakery stop, Kona drives an additional 60 - 54 = 6 miles.

Question and rationale: The question is: Giselle had 20 female doves in a birdhouse. After a month, the doves laid 3 eggs each. If 3/4 of the eggs hatched, calculate the total number of doves Giselle has now.
Step-by-step reasoning process: If Giselle had 20 doves that laid 3 eggs each, the total number of eggs in the birdhouse is 20 * 3 = 60 eggs. If 3 / 4 of the eggs hatched into birds, their total number is 3 / 4 * 60 = 45. In the birdhouse, there are 20 initial doves + 45 new squabs = 65 birds.

The question is: The length of the straight part of a river is three times shorter than the crooked part. If the river is 80 miles long, how long is the straight part of the river?
Step-by-step reasoning process: Let's say the river's length in the straight part of the river is x. The total length of the river is the length of the straight part plus 3 times the length of the straight part for the crooked part, which is x + 3x = 80. The total length of the river is 4x = 80. The straight part of the river is x = 80 / 4 = 20 miles.
