30 min: 60min-30min= 30 min and 30 min is half an hour. So since 30 min is half an hour you divide 4 by 2 and get 2 miles.
45 min: 60min-45min= 15 min. 15 is one quarter of an hour so, since you are going 4mph. So you do 4mph divided by another for because there are four quarters in one hour, which gives you one mile. Then you 1 mile 3 times because 15+15+15=45. So the answer is 3 miles.
2 hours: 2x4= 8 miles
3 hours: 3 hours x 4mph= 12 miles
Answer:
Step-by-step explanation:
Neither blue plot line is dashed, so we eliminate any equation that contains the symbols "<" or ">". Remove A and C
B and D (actually all options) have y ≤ -x + 4 which is a line with slope -1 any y intercept 4. This represents the area below the line running from (0, 4) to (4, 0)
Which leaves us to select from y ≥ x + 2 for option B or y ≤ x + 2 for option D
As the shaded area is <em>below</em> the line we choose <u>option D</u>
