Sophia trains with her friend Aisha on a 5-kilometer trail near their school.
Aisha starts running right after school and runs an average of one kilometer in seven minutes.
Sophia leaves 10 minutes later and runs at a steady pace shown in the table below.
Write each function as a linear equation where x is the number of kilometers and y is the number of minutes.
Who runs faster? Explain.
