Jennie, Lisa, and Jisoo have decided to race from the top of a hill to its bottom. Jennie rides a bicycle through a downhill trail which is 700 meters long. It takes her 5 minutes to reach the bottom of the hill, Lisa takes a cable-car and the cable car follows a straight wire from the top to the bottom which is 400 m long. It takes her 3 minutes. Jisoo drives a car through a winding road that is 1500 m long and it takes her 6 minutes Find out who has the highest speed, and who has the highest velocity, among the three of them.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

so, converting firstly the mixed fractions to improper fractions and then "adding".
