Answer:
C. 5
> 15
Step-by-step explanation:
In the given series of inequalities, the inequality sign determines the final outcome.
A. 4
- 2 < 10
4
< 12
< 3
Since
< 3, then the inequality is false
B.
+ 9 < 12
< 3
Since
< 3, then the inequality is false
c. 5
> 15
> 3
Since
> 3, then the inequality is true
D. 6 > 2
3 > 
Since
< 3, then the inequality is false
Thus, the only inequality that is true is option C.
Distance from home to store = 4 * 0.5 = 2 miles.
Time taken to return home = (2/12) * 60 =10 minutes.
Total distance traveled = 2 * 2 = 4 miles.
Total time taken = 30 + 10 = 40 minutes.
Average speed for entire trip = total distance / total time in hours.
