If it took t hours to travel to college then it took 7-t to return home.
The distance travelled is the same so 15t=6(7-t), 15t=42-6t, 21t=42, t=2 hours.
So travel to college took 2 hours and it took 5 hours to return home.
Find x for each range value.
for example, 11.4 = 4x-3⇒ x=14.4/4 =3.6
all the x values together constitute the domain.
But, in this case, only the last option has 3.6
hence, answer is E

Write equations for the given information to solve (using J for Jeanine and M for Marc):
J=2M
J+M= 24
Now substitute 2M in for J in the second equation:
2M+M=24, 3M=24, M=8
Remember that J=2M, so if M=8, J=16.
So Jeanine is 16 and Marc is 8
