Question: A highway is being extended from its current length of 200 miles up to 650 miles. 50 miles are built on the first day, and three times this amount are built on the second day. How many miles still need to be added to the highway to finish extending it?
Answer: The length of the highway that needs to be constructed is 650 – 200 = 450 miles. After the first day, there are still 450 – 50 = 400 miles that need to be constructed. On the second day, 50 miles * 3 = 150 miles are added to the highway. This means that 400 – 150 = 250 miles still need to be added to the highway. The answer is 250.
Q: A rectangular flowerbed in the city park is 4 meters wide. Its length is 1 meter less than twice its width. The government wants to fence the flowerbed. How many meters of fence are needed?
A:
Twice the width is 4 x 2 = 8 meters. The length of the rectangular flowerbed is 8 - 1 = 7 meters. Since the rectangular flower bed has 2 equal lengths, then it needs 7 x 2 = 14 meters of fence. The rectangular bed has also 2 equal widths, so it needs 4 x 2 = 8 meters of fence. Therefore, the rectangular flower bed needs a total of 14 + 8 = 22 meters of fence. The answer is 22.
