Q: Martin went on an eight-hour business trip. During the first half of the trip, he traveled at a speed of 70 kilometers per hour and during the second half at a speed of 85 kilometers per hour. How many kilometers did he travel during the journey?
A: Half of the trip lasts for 8 * 0.5 = 4 hours. During the first half, Martin did 4 * 70 = 280 kilometers. And during the second half 4 * 85 = 340 kilometers. In total Martin traveled 280 + 340 = 620 kilometers during his business trip. The answer is 620.
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.
