A marathon runner runs 6 miles south and then 8 miles east How far is the runner from the starting point?

(Distance)2 = (6)2 + (8)2 = 36 + 64 = 100
Distance = sqrt(100) = 10 miles
To be honest about it, this is only an approximation. The formula used here is only valid
on a flat surface, and we all know that the earth is a spherical surface.
Even worse than that ... the formula is only valid if the two directions are perpendicular (90°)
to each other. But north and east are only perpendicular at the equator; the farther you are
from the equator, the less perpendicular they are.
To show you how bad it can get: If you start at the north pole, go 6 miles south,
and then go 8 miles east, you wind up only 6 miles from where you started.
In order to answer this question accurately, you have to know exactly where on earth
the marathon runner started from, and then you have to use spherical trigonometry.
I'm sure you'll be happy that I'm not going to do that. It's valid because we don't know
where he started from.
We'll just say: The answer is "approximately 10 miles", and the closer our runner is
to the equator, the more accurate this answer is.

Omar drives a car five miles north then five miles west then five miles south How many miles is he likely to be from his starting point?
The obvious answer is 5 miles. The not-so-obvious part is it depends on where he is when he starts. If he is on the equator, he is five miles from his point of origin. If his starting point was the south pole, and he drives five miles north, then west, then south, he will arrive back at his starting point. Before you disagree, consider that he is driving on a sphere not a flat plain.
Mary walks 4 miles north and then turns and walks 5 miles west How far is she from her original starting point?
If she started from the south pole, then she'll wind up 4 miles from her starting point after this series of maneuvers. If she started on or near the equator, then the final distance is roughly 6.4 miles.
A boat travels due east for a distance of 15 miles It then travel due north for a distance of 20 miles at which point it drops anchor How many miles is the boat far from it's starting point?
25 miles
A boat travels due east for a distance of 15 miles its then travels due north for a distance of 20 miles at which point it drops anchor how many miles is the boat from it's starting point?
This is where you apply the pythagorean theorem: d = √(152 + 202) ∴d = √(225 + 400) ∴d = √(625) ∴d = 25 So the boat is 15 miles from it's starting point
Willie drove his car 15 miles north then turned right 7 miles east how far is he in a straight line from his starting point round answer to the nearest hundredth place?
So this uses pythagoras theorem. x = sqrt15 + sqrt 7. So he was 16.55 miles from starting point
A marathon runner runs 6 miles south and 8 miles east How far is the runner from the starting point?
14 miles on the route he took. 10 miles if you mean in a straight line.

I have been running on a treadmill and i am up to 6 miles will i be able to run a 5k outdoors I don't want to win I just want to finish?
If you constantly run on a treadmill and practice, running six miles is a good starting point to being able to run a 5k marathon.
How many nautical miles from marathon fl to naples fl?
The distance between the above places is approximately equal to 4687 nautical miles. To convert miles to nautical miles, multiply the miles by 0.86. This is point to point straight distance. The actual distance will change according to the route.
How much miles Niagara from Toronto?
75 miles approximately depending on your starting point
Would 300 Miles get you to Flroida?
That depends what your starting point is.

What is the driving distance between Tampa and Marathon Florida?
The distance between the above places is approximately equal to 207 nautical miles. To convert miles to nautical miles, multiply the miles by 0.86. This is point to point straight distance. The actual distance will change according to the route.
How many miles to Killarney Manitoba?
That would depend on your starting point.
A car travels 5 miles north and 12 miles west. How far is the car from its starting point?
13 miles
Where is point of no return?
Probably safe to say mid-point. When it's as far to go back to your start point as to go on to your end point. I would point out that the "no return" part does not imply the mid-point. It is the point when it is no longer possible to return to your starting point safely. If I am flying 150 miles away and have enough fuel to travel 200 miles (and some reserve for safety) then the point of no return is 100 miles out, not 75 miles. It is the point when I can no longer return to my starting point safely and must continue on to the end point.
