What is the largest dimension of which you have personal knowledge? Have you run a mile? Hiked 10 miles? Run a marathon?
To tell about the largest dimension that we have personal knowledge. We need to tell about a mile,hiked 10 miles and run a marathon when we run a distance.
Answer to Problem 1RQ
The largest dimension based on personal knowledge is mile or kilometer. A normal person can easily run a mile in routine. For hike 10 miles, small practice is required but for run the marathon, regular practice is required based on gradual increase in the miles.
Explanation of Solution
The largest dimension based on personal knowledge is mile or kilometer because in a normal routine a person may walk or run 3 to 4 miles. There is another fact that the next dimension after kilometer is megameter which is 1000 times of kilometer (approximately is equal to the radius of the Earth). To run a megameter is impossible for any person at personal level in the World.
Yes, we (as a normal person) have run a mile in our routine. This is essential because a mile is equal to 1.6 kilometer (approximately) but when we hike this distance by 10 miles then it will not be so easy for a normal person. I have run 10 miles only once.
Normally, marathon run lies between 26 miles to 30 miles. I have never run a marathon because for this run, a regular practice is required. To achieve the target of marathon, we should start the run-practice from 5 miles and should increase the distance gradually on weekly basis.
Hence, we conclude that the largest dimension based on personal knowledge is mile or kilometer. A normal person can easily run a mile in routine. For hike 10 miles, small practice is required but for run the marathon, regular practice is required based on gradual increase in the miles.
Conclusion:
The largest dimension based on personal knowledge is mile or kilometer. A normal person can easily run a mile in routine. For hike 10 miles, small practice is required but for run the marathon, regular practice is required based on gradual increase in the miles.

- I'm having trouble completing the problem I've attached a picture of below. I was able to find the the Earth's average speed in m/s relative to the sun by doing (2pi*(1.49x10^11))/31536000. But I am struggling to find the average velocity for the same thing over a period of one year in m/s. I was wondering how to calculate that? I've tried doing the (final velocity-initial velocity)/2 but the program doesn't accept my answer when using that approach.arrow_forwardWhile a meter is the fundamental unit of length, most distances traveled by humans are measured in miles or kilometers. Why do you think this is?arrow_forwardCalculate the angle a person needs to lean from the vertical when 1. walking a 14 m (radius) circular track at 22 mins per mile, and Enter to 2 significant figures Angle with respect to the vertical = = 0.85 ! No, that's not the correct answer. O 2. running at 4 min per mile. Enter to 2 significant figures Angle with respect to the vertical = 6.8 Use 1 mile = 1609.4 m Sense-making: Do your results for the leaning angle during walking agree with your observations about people walking on circular tracks?

In Part 1 we will pretend to shrink the solar system until its center piece, the Sun, is 67.3 cm in diameter. This will represent the Sun which is 1,390,000 km in diameter. The scale of our model is thus: 67.3 cm = 4.84 x 10-5 cm km Scale 1, 390, 000 km To find the size or distance between objects in centimeters for the model, simply multiply the actual size or distance in kilometers by the scale factor above. 1.
