Consider the Q and A. Q: Barry and his friend, Jim, went horseback riding across central Texas. They traveled at 5 miles per hour for 7 hours, and then stopped for the evening. The next day, they traveled at 6 miles per hour for 6 hours, and then at half that speed for another three hours, before stopping to rest for the night. On the third and final day, they traveled for 5 hours at 7 miles per hour. In total, how far did they travel, in miles, during their horseback riding trip?
A: 115
What is the step-by-step reasoning process?
Step-by-step reasoning process: On the first day, they traveled 5 * 7 = 35 miles. On the first part of the second day, they traveled 6 * 6 = 36 miles. The second part of the second day, at half their morning speed, they traveled (6 / 2) * 3 = 9 miles. On the final day, they traveled 5 * 7 = 35 miles. In total, they traveled 35 + 36 + 9 + 35 = 115 miles.

Consider the Q and A. Q: Alexander was 50 inches on his 8th birthday. If he grows 1/2 a foot a year, how many inches tall will he be on his 12th birthday?
A: 74
What is the step-by-step reasoning process?
Step-by-step reasoning process: He grows six inches a year because 12 x .5 = 6. He will grow 24 inches between his 8th and 12th birthday because 4 x 6 = 24. He will be 74 inches tall because 50 + 24 = 74.

Consider the Q and A. Q: Mcgregor and Floyd were assigned 89 books to read for the week. If Mcgregor was able to finish 34 while Floyd was able to finish 32, how many books do they still have to read?
A: 23
What is the step-by-step reasoning process?
Step-by-step reasoning process: They both finished reading a total of 34 + 32 = 66 books. Therefore, they still have to read a total of 89 – 66 = 23 books.

Consider the Q and A. Q: Barbie enjoys buying jewelry. One day, she bought 12 pairs of earrings, and gave half of them to Alissa, making Alissa's total number of collections to be triple the number of earrings she was given. How many earrings does Alissa have now?
A: 36
What is the step-by-step reasoning process?
Step-by-step reasoning process:
If 1 pair of earrings equals 2 earrings, then Barbie bought 12 * 2 = 24 earrings. Half of 24 earrings is 24 / 2 = 12 earrings. If receiving 12 earrings tripled Alissa's collection, then she now has 12 * 3 = 36 earrings.
