Sam and Jeff had a skipping competition at recess. The competition was split into four rounds. Sam completed 1 more skip than Jeff in the first round. Jeff skipped 3 fewer times than Sam in the second round. Jeff skipped 4 more times than Sam in the third round. Jeff got tired and only completed half the number of skips as Sam in the last round. If Sam skipped 16 times in each round, what is the average number of skips per round completed by Jeff? Give the rationale and then the answer.
Let's think step by step. In round one, Jeff completed 16 - 1 = 15. In round two, Jeff completed 16 - 3 = 13. In round three, Jeff completed 16 + 4 = 20. In round four, Jeff completed 16 / 2 = 8. Jeff completed 15 + 13 + 20 + 8 = 56 skips in total. Jeff skipped an average of 56 / 4 = 14 skips per round.. The answer is: 14.

A man decides to try and do everything off his bucket list while he is still young and fit enough to finish it all. One of his goals was to climb the seven summits. He realizes first he has to get in shape to do it and it takes him 2 years of working out to get healthy enough to take up mountain climbing. He then spends twice that long learning how to be a technically proficient mountain climber. After that he starts with the simplest mountain on the list and climbs them all. He spends 5 months climbing each mountain. After that he takes 13 months learning to dive and dives through all the caves he wants in 2 years. How much time did it take to get through all these goals? Give the rationale and then the answer.
Let's think step by step. He spent 2 * 2 = 4 years learning to climb. He spends 5 * 7 = 35 months climbing all 7 mountains. After a 13 month break, he starts diving so that is 35 + 13 = 48 months. That means it is 48 / 12 = 4 years. So in total it all took 2 + 4 + 4 + 2 = 12 years.. The answer is: 12.

Brad's car broke down on an isolated road. At the time, Brad was traveling with Jim and Marcus. So, the three decided to push the car back into town, which was 10 miles away. For the first three miles, Brad steered as Jim and Marcus pushed at a speed of 6 miles per hour. Then, for the next 3 miles, Jim steered, as Brad and Marcus pushed at a speed of 3 miles per hour. For the last four miles, Marcus steered as Brad and Jim pushed at a speed of 8 miles per hour. How long did it take, in hours, to push the car back to town? Give the rationale and then the answer.
Let's think step by step. Three miles at 6 miles per hour is 3 / 6 = 1 / 2 hours. Then, 3 miles at 3 miles per hour is 3 / 3 = 1 hour. The last 4 miles at 8 miles per hour is 4 / 8 = 1 / 2 hour. In total, it took them 1 / 2 + 1 + 1 / 2 = 2 hours to push the car back to town.. The answer is: 2.
