Answer:
~ 3 miles per hour
Step-by-step explanation:
Because you walk 1.5 miles in half an hour, it is fair to assume that you will continue this rate and walk 3 miles in the full hour. Therefore, you are walking at a rate of 3 miles per hour.
1/10 th of a mile every minute
-1 < x < 4.
- 6 < 2x - 4 <4
2x - 4 < 4
2x < 8
x < 4. Also we have:
2x - 4 > -6
2x > -2
x > -1.
