You jog at 6.6 mi/h for 5.0 mi, then you jump into a car and drive for another 5.0 mi. With what average speed must you drive if your average speed for the entire 10.0 miles is to be 10.4 mi/h? answer is 24.5 mi/h. WHY??

the answer is B. The parentheses represent that it is not inclusive. So since its -7<x<7 (not inclusive on both sides) then you use parentheses on both sides. If it were -7<=x<=7 then it would be D. hopefully that makes sense? :)
