John releases 3 videos on his channel a day. Two of them are short 2 minute videos and 1 of them is 6 times as long. Assuming a 7-day week, how many minutes of video does he release per week? Give the rationale and then the answer.
Let's think step by step. He releases 1 video that is 2 * 6 = 12 minutes long. So each day he releases 2 + 2 + 12 = 16 minutes of videos. That means he releases 16 * 7 = 112 minutes of videos.. The answer is: 112.

Georgia is sick and coughs 5 times a minute. Her brother Robert is also sick but he coughs twice as much as her. After 20 minutes, how many times have they coughed? Give the rationale and then the answer.
Let's think step by step. Robert coughs twice as much as Georgia who coughs 5 times so Robert coughs 2 * 5 = 10 coughs per minute. Georgia coughs 5 times and Robert coughs 10 times so together they cough 5 + 10 = 15 times per minute. After 20 minutes they will have coughed 15 * 20 = 300 coughs.. The answer is: 300.

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? Give the rationale and then the answer.
Let's think step by step. 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.
