Which of the following inequalities is shown in the graph? 1) y ≤1/2x-2 2) y ≤-2x+1/2 3) y ≤2x+1/2 4) y ≥-2x+1/2

answer is more than one

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
