Answer the following question.
John trains for ultramarathons. He starts only able to run 8 hours straight but eventually increases that by 75%. He also increases his speed of 8 mph by 4 mph. How far can he run now?
Step-by-step reasoning process: He increases the time he can run by 8 * .75 = 6 hours. So he can now run 8 + 6 = 14 hours. His speed is now 8 + 4 = 12 mph. So he can run 14 * 12 = 168 miles.
The answer is 168.

Answer the following question.
Melissa works on a poultry farm. She drives to town twice each month to buy supplies. If it takes her 3 hours to drive to town and back, how many hours does Melissa spend driving in a year?

Answer the following question.
James does chores around the class. There are 3 bedrooms, 1 living room, and 2 bathrooms to clean. The bedrooms each take 20 minutes to clean. The living room takes as long as the 3 bedrooms combined. The bathroom takes twice as long as the living room. He also cleans the outside which takes twice as long as cleaning the house. He splits the chores with his 2 siblings who are just as fast as him. How long, in hours, does he work?
Step-by-step reasoning process: It takes 3 * 20 = 60 minutes to clean the living room. So it is 60 / 60 = 1 hour. The bathroom takes 1 * 2 = 2 hours. So all together the inside takes 1 + 1 + 2 = 4 hours. The outside takes 4 * 2 = 8 hours. So the chores take 4 + 8 = 12 hours. He splits it 1 + 2 = 3 ways. So he works 12 / 3 = 4 hours.
The answer is 4.

Answer the following question.
Zion made a triangular-shaped house of cards with the base having a measurement of 40 centimeters and a height of 20 centimeters. If two of his friends also built similar shaped houses, what's the total area of the triangular houses that Zion and his friends made (the area of a triangle is 1/2 * width * height)?
Step-by-step reasoning process: Since the area of a triangle is given by 1 / 2 base * height, the area of the triangular - shaped house of cards that Zion made is 1 / 2 * 40 * 20 = 400 square centimeters. If two of his friend also built similar shaped houses, the total area of their triangular - shaped house of cards is 400 + 400 = 800 square centimeters. Together with Zion, they all built triangular - shaped houses of cards with a combined area of 800 + 400 = 1200 square centimeters.
The answer is 1200.
