Q: Ray has 175 cents in nickels. Ray gives 30 cents to Peter, and he gives twice as many cents to Randi as he gave to Peter. How many more nickels does Randi have than Peter?
A: Ray gave 30 * 2 = 60 cents to Randi. Randi has 60 / 5 = 12 nickels. Peter has 30 / 5 = 6 nickels. Randi has 12 - 6 = 6 more nickels than Peter. The answer is 6.

Q: Jane had a 500 page book to read. The first half of the book Jane read with a speed of 10 pages per day, and the second half with a speed of 5 pages a day. How many days did Jane spend reading this book?
A: Half of the book means 500 / 2 = 250 pages. Reading the first half took Jane 250 / 10 = 25 days. Reading the second half of the book took Jane 250 / 5 = 50 days. So in total Jane needed 25 + 50 = 75 days to read the whole book. The answer is 75.

Q: Jefferson hires a carriage to go to the church. It is 20 miles away. The horse can go 10 miles per hour. It cost $30 per hour plus a flat fee of $20. How much did he pay for the carriage?
A:
He paid for 20 / 10 = 2 hours. That means the hourly fee was 30 * 2 = $60. So the total cost was 60 + 20 = $80. The answer is 80.
