Answer the following question.
A Lamplighter monkey has long arms and can swing from branch to branch at a speed of 10 feet per second. But when the monkey is frightened, it will run along the branches at a speed of 15 feet per second. If a Lamplighter monkey runs for 5 seconds to evade a predator, then swings for another 10 seconds to add distance between itself and the predator, how far, in feet, will the monkey travel?
Step-by-step reasoning process: At a speed of 15 feet per second, for 5 seconds, the monkey will travel 5 * 15 = 75 feet. At a speed of 10 feet per second for 10 seconds, the monkey will travel 10 * 10 = 100 feet. In total, the monkey will travel 75 + 100 = 175 feet.
The answer is 175.

Answer the following question.
Reese joined a Pinterest group where members contributed an average of 10 pins per day. The group owner deleted older pins at the rate of 5 pins per week per person. If the group has 20 people and the total number of pins is 1000, how many pins would be there after Reese had been a member for a month?
Step-by-step reasoning process: In a day, the total number of new pins is 10 * 20 = 200. There will be 30 * 200 = 6000 new pins after a month. The total number with old pins present is 6000 + 1000 = 7000 pins. If the owner deletes five pins every week, the total number of deleted pins in a week is 5 * 20 = 100 pins. After a month, the number of deleted pins will be 100 * 4 = 400. The number of pins after the old pins are deleted is 7000 - 400 = 6600 pins.
The answer is 6600.

Answer the following question.
For this month, Lily wants to finish reading twice as many books as she finished last month. If she finished reading 4 books last month, what will be the total number of books that she will finish for two months?
Step-by-step reasoning process: This month, Lily wants to finish reading 4 x 2 = 8 books. So, for two months, she will finish reading 4 + 8 = 12 books.
The answer is 12.
