A cyclist is riding on a straight trail that is 30 miles long. She starts at mile marker 9. She stops for lunch at the midpoint of the trail. She gets a flat tire midway between
where she stopped for lunch and the end of the trail.
At what mile marker did she get the flat tire?

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

i would be 2,000 just get the square root of 50 which is 2500 and the divid 4/5 and last thing multiply the answer you get for that by the square root of 50
