[Question]A pair of dogs are barking back and forth at each other from across the street. The poodle barks twice for every one time the terrier barks. The terrier’s owner hushes it every second time it barks. She has to say “hush” six times before the dogs stopped barking. How many times did the poodle bark?
[Answer]The terrier barked twice as many times as it was told to hush, so it barked 6 * 2 = 12 times. The poodle barked two times for every terrier bark, so it barked 12 * 2 = 24 times. The answer is 24.
Q: Bill gets paid $20 every hour he works up to a total of 40 hours, after which he gets paid double that amount per hour. How much does Bill get paid for a 50-hour workweek?
A: Bill makes $20 an hour for the first 40 hours, meaning he gets paid 40 * 20 = 800 dollars. For the remaining 10 hours, Bill gets paid double the amount of $20, meaning he makes 20 * 2 = 40 dollars an hour. Since he worked 10 hours at that $40 an hour rate, that means he gets paid 10 * 40 = 400 dollars for the final 10 hours. In total, this means Bill gets paid 800 + 400 = 1200 dollars for his workweek. The answer is 1200.
Question: Roger had a 6-hour drive planned out. He didn't want to listen to music so he downloaded several podcasts. The first podcast was 45 minutes long. The second podcast was twice as long as that. The third podcast was 1 hour and 45 minutes long. His fourth podcast is 1 hour long. How many hours will his next podcast have to be to fill up the full 6 hours?
Answer:
The second podcast was twice as long as the first so 2 * 45 = 90. 1 hour is 60 mins. So his 1 hour and 45 min podcast is 60 + 45 = 105 minutes long. So far he has downloaded 45 + 90 + 105 + 60 = 300 min. If he converts 300 min to hours then he has 300 / 60 = 5 hours of podcasts downloaded. He has 5 hours of podcasts and his drive is 6 hours so he will need 6 - 5 = 1 more hour of podcasts. The answer is 1.
