Arithmetic Reasoning
In working as an ASVAB tutor, I see the importance of presenting an in-depth review of the Arithmetic Reasoning section of the ASVAB. Word problems can be challenging questions for many students. Yesterday I presented an Arithmetic Reasoning question that covers the skill of time.
The question asks:
Jessica worked a total of 42 hours in 5 days. What was the average amount of hours that she worked each day?
- 8 hours 2 minutes
- 8 hours 15 minutes
- 8 hours 24 minutes
- 8 hours 30 minutes
To solve this problem, it is necessary to divide 42 by 5.
42 divided by 5 is 8 2/5 hours.
To find the correct answer to this question, it is necessary to change the fraction into minutes
An hour has 60 minutes
2/5 needs to be set equal to x/60 to figure out the minutes
2/5 = x/60
Cross multiply and solve for x.
2 x 60 = 5x
120 = 5x
Divide by 5
24 = x
The correct answer is choice C. 8 hours and 24 minutes.
