Reasoning and answer: If in one hour he covers 10 miles and rides for 15 miles at the rate of 10 miles per hour, then the time taken for the 15 miles will be 15 / 10 = 1.5 hours. The time in minutes is 1.5 * 60 = 90 minutes. The time taken for the remaining 20 miles at a rate of 10 miles per hour is 20 / 10 = 2 hours. The time in minutes is 2 * 60 = 120 minutes. The total time taken for the whole journey is the first 30 minutes + 90 + 30 minutes for resting + 120 minutes = 270 minutes.
The answer: 270

Question: Mr. Isaac rides his bicycle at the rate of 10 miles per hour for 30 minutes. If he rides for another 15 miles, rests for 30 minutes, and then covers the remaining distance of 20 miles, what's the total time in minutes took to travel the whole journey?
There are 60 minutes in an hour and she packs chocolate in 5 - minute increments. So that's 60 / 5 = 12 5 minute increments in 1 hour. 12 chocolates make 1 dozen and she packages 2 dozen in 5 minutes so that's 12 * 2 = 24 chocolates in 5 minutes. 12 5 minute increments are in an hour and she packages 24 chocolates in 5 minutes so she can package 12 * 24 = 288 individual chocolates in 1 hour. If she packages 288 individual chocolates in 1 hour then in 4 hours she can package 288 * 4 = 1,152 individual chocolates.
The answer: 1152
Reverse engineering the question: Wendy works at a chocolate factory packing chocolates. She can package 2 dozen chocolates in 5 minutes. How many individual chocolates can she package in 4 hours?
Reasoning and answer: To buy 100 pencils the school needs 100 * $1.80 = $180.00. Each ice pop sells for $1.50 but costs $.90 to make, for a net profit of $1.50 - $.90 = $.60. So in order to raise $180.00, the school will need to sell $180.00 / $.60 per ice - pop = 300 ice - pops.
The answer: 300

Question: To raise money, a school is selling ice-pops for $1.50. It costs 90 cents to make each pop, and the money from the pops will be used to buy pencils, which cost $1.80 each. How many pops must be sold to buy 100 pencils?
Cindy gave her four friends 80 marbles each, a total of 4 * 80 = 320 marbles. She was left with 500 - 320 = 180 marbles. Four times the number of marbles she has remaining is 180 * 4 = 720.
The answer: 720
Reverse engineering the question: Out of the 500 marbles that Cindy had, she gave her four friends 80 marbles each. What's four times the number of marbles she has remaining?
Reasoning and answer: If the tree's 10 branches have 40 sub - branches each, the total number of sub - branches on the tree is 10 * 40 = 400. Since each sub - branch has 60 leaves, the tree has 60 * 400 = 24000 leaves. If there are four trees on the farm with the same number of leaves, they all have 24000 * 4 = 96000 leaves.
The answer: 96000

Question: A tree on a farm has 10 branches. Each branch has 40 sub-branches with 60 leaves each. If the total number of trees on the farm is 4 and they have the same number of leaves, calculate the total number of leaves on all the trees.
Reasoning and answer: First find the total revenue from the matinee tickets: $5 / ticket * 200 tickets = $1000. Then find the total revenue from the evening tickets: $12 / ticket * 300 tickets = $3600. Then find the total revenue from the 3D tickets: $20 / ticket * 100 tickets = $2000. Then add the cost of each group of tickets to find the total cost: $1000 + $3600 + $2000 = $6600.
The answer: 6600
