Elisa ran a total of 8 4/5 miles on Saturday and Sunday. If she ran 5 1/4 miles on Saturday, how many miles did she run on Sunday?

Step-by-step explanation:

Given

Elisa run a total of miles on Saturday and Sunday.

If she runs miles on Saturday

Then, distance traveled on Sunday is given by

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
