8x >/= 120
x >/= 15
She must work 15 hours or more to earn at least $120
( 4.625, - 3.75 )
the midpoint of (x₁, y₁ ) and (x₂, y₂ ) is
[
(x₁ + x₂ ),
(y₁ + y₂ ) ]
here (x₁, y₁ ) = (5.5, - 4.75 ) and (x₂, y₂ ) = (3.75, - 2.75 )
[
(5.5 + 3.75 ),
(- 4.75 - 2.75 ) ]
= (4.625, - 3.75 ) ← midpoint of HX
Since she drove 60.8miles per hour(182.4÷3=60.8)
then she would drive 668.8 miles in 11 hours
(60.8×11=668.8
