[Question]Helga works for a newspaper company. She can write 5 articles every 30 minutes, and she usually works 4 hours a day 5 days a week. If Helga worked an extra 2 hours last Thursday, and an extra 3 hours last Friday, how many articles was she able to write this week?
[Answer]Helga writes 5 x 2 = 10 articles per hour. And she can write 10 x 4 = 40 articles every 4 hours. So, the total number of articles she usually writes for a week is 40 x 5 = 200 articles. She was able to write 10 x 2 = 20 articles on her extra 2 hours last Thursday. And she was able to write 10 x 3 = 30 articles on her extra hour last Friday. So, the total number of articles she was able to write on her extra hours is 20 + 30 = 50. Therefore, she was able to write a total of 200 + 50 = 250 this week. The answer is 250.

[Question]Jackie can do 5 push-ups in 10 seconds. How many push-ups can she do in one minute if she takes two 8-second breaks?
[Answer]
There are 60 seconds per minute, so Jackie's push - up routine takes 1 * 60 = 60 seconds. Her breaks last 2 * 8 = 16 seconds. She does push - ups for 60 - 16 = 44 seconds.
