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.

Every hour past noon shadows from a building stretch an extra 5 feet, starting at zero at noon. How long are the shadows from the building 6 hours past noon in inches? Give the rationale and then the answer.
Let's think step by step. If the shadows lengthen by 5 feet per hour, this means that in 6 hours the shadows would have lengthened from zero to 5 * 6 = 30 feet. Since there are 12 inches in every foot, this means the building's shadow would be 30 * 12 = 360 inches in length.. The answer is: 360.

Eunice has 10 eggplant seeds and 4 pots. How many seeds will be planted in the fourth pot if 3 seeds can be planted in 1 pot? Give the rationale and then the answer.
Let's think step by step. Eunice can plant a total of 3 pots x 3 seeds = 9 seeds in three pots. So, only 10 - 9 = 1 eggplant seed will be planted in the fourth pot.. The answer is: 1.
