[Question]Colin ran his first mile in 6 minutes. He ran his next two miles in 5 minutes each and finished his 4th mile in 4 minutes. What was the average time it took him to run a mile?
[Answer]His first mile was in 6 minutes, then 5 minutes, another 5 minutes and his final mile was 4 minutes so it took him 6 + 5 + 5 + 4 = 20 minutes. It took 20 minutes to run 4 miles so his average time was 20 / 4 = 5 minutes per mile. The answer is 5.

[Question]Jackie loves to climb trees. She climbed a 1000 foot tall tree. Then she climbed 2 trees that were half as tall as the first tree. She finished by climbing a tree that was 200 feet taller than her first tree. What was the average height of the trees that Jackie climbed?
[Answer]Jackie climbed 2 trees that were 1 / 2 * 1000 feet = 500 feet tall each. Jackie climbed a final tree that was 1000 + 200 feet = 1200 feet. In total, the 4 trees Jackie climbed were 1000 feet + 500 feet + 500 feet + 1200 feet = 3200 feet. The average height tree that Jackie climbed was 3200 feet / 4 trees = 800 feet tall. The answer is 800.
