Violet is watching the sand in an hour glass drain from the upper portion to the lower portion of the class. she wondered how fast the sand is draining. which unit rates would be reasonable four violet to use to describe how fast the sand is draining from the upper portion pto the lower portion of the glass?

in 4 days he will run   12/14

step-by-step explanation:

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.
