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

Please note that all of the answers should read "less than or equal".

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?

It should be "D".

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