Q: From March to August, Sam made $460 doing 23 hours of yard work. However, from September to February, Sam was only able to work for 8 hours. If Sam is saving up to buy a video game console that costs $600 and has already spent $340 to fix his car, how many more hours does he need to work before he can buy the video game console?
A: Sam makes $460 / 23 hrs = $20 / hr. From September to February, Sam made 8hrs x $20 / hr = $160. From March to February, Sam made a total of $460 + $160 = $620. After fixing his car, he was left with $620 - $340 = $280. Sam needs another $600 - $280 = $320. Sam needs to work another $320 / $20 / hr = 16 hours. The answer is 16.

Q: Joseph wants to go to Boston for a road trip. If he takes route A, it will take him 5 hours to arrive; but if he takes route B, it will only take him 2 hours to arrive at his destination. How much time will he save if he takes route B to Boston and back to his home?
A:
He will spend 5 x 2 = 10 hours if he takes route A. Meanwhile, he will spend 2 x 2 = 4 hours if he takes route B. Therefore, Joseph can save 10 - 4 = 6 hours if he takes route B both ways. The answer is 6.
