50 and 4/5 miles i 4 hours'

12.5 feet

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

yes   because as the functions are graphed they eventually will intersect unless otherwise
