Bills' school is 10 miles from his home. He travels 4 miles [#permalink]  22 Dec 2007, 15:33
Bills' school is 10 miles from his home. He travels 4 miles from school to football practice, and then 2 miles to friend's house. If he is then x miles from home, what is the range of possible values for x?

a) 2<x<10

b) 4<x<10

c) 4<x<12

d) 4<x<16

e) 6<x<16

My problem is: When Bill travels 4 miles from school to football practice, how do we know that he travels toward his HOME or against his HOME?

D

max=10+4+2=16
min=10-4-2=4

Therefore, 4<=x<=16

It should be "D".

Let him move in extremes, one towards the home and other totally opposite.
