Answer:

d=√73=8.544

Step-by-step explanation:

Find distance (d) between market (0,8) , court house(6,5) and library(6,-1)

d between two pint is :

d=√(x2-x1)²-(y2-y1)²

d between market and court house:

d=√(6-0)²+(5-8)²

d=√36+9=√45 = 6.7082 ≅6.71 rounded to the nearest hundredths

d between courthouse and the library:

d=√(6-6)²+(-1-5)²

d=√36=6

the distance that Runner A ran=6.71+6=12.71

the distance from the library to the school:

d=√(6-(-2))²+(-1-(-4))²

d=√8²+3²

d=√64+9

d=√73=8.544 ( rounded to the nearest hundredth)

Runner B went  8.544 further than Runner A before stopping at school ( which is the distance between the library and the school.
