[Question]Susan walked to the market to buy five dozen peaches. To carry them home, she brought two identically-sized cloth bags and a much smaller knapsack. Into the knapsack she placed half as many peaches as she placed in each of the two cloth bags. How many peaches did she put in the knapsack?
[Answer]5 dozen peaches is 5 * 12 = 60 peaches. Let "x" be the number of peaches put into the knapsack. Thus, the total number of peaches is x + (2 * x) + (2 * x) = 60. Simplifying the expression, we see that 5 * x = 60. Dividing each side of the equation by 5, we see that x = 12 peaches,. The answer is 12.

[Question]Bill's roof can bear 500 pounds of weight. If 100 leaves fall on his roof every day, and 1000 leaves weighs 1 pound, how many days will it take for his roof to collapse?
[Answer]First, find how many leaves the roof can hold: 500 pounds * 1000 leaves / pound = 500000 leaves. Then divide that by the number of leaves that fall each day to find how many days before the roof collapses: 500000 leaves / 100 leaves / day = 5000 days. The answer is 5000.

[Question]A man intends to complete a journey of 24 km in 8 hours. If he travels at a speed of 4km/hr for the first four hours, at what speed does he need to travel for the remainder of the journey to be right on time?
[Answer]
He covers 4km / hr * 4hrs = 16km in the first 4 hours. He has 24 - 16 = 8km left to cover. He has 8 - 4 = 4 hours to cover the remaining 8km. He has to travel at a speed of 8km / 4hrs = 2km / hr to be right on time. The answer is 2.
