Question: Kim drives 30 miles to her friend's house. On the way back she has to take a detour that is 20% longer. She spends 30 minutes at her friend's house. She drives at a speed of 44 mph. How long did she spend away from home?
Answer: Step-by-step reasoning process: The trip back was 30 * .2 = 6 miles longer than the trip there. So it was 30 + 6 = 36 miles. So the total drive was 30 + 36 = 66 miles. That means she drove for 66 / 44 = 1.5 hours. She stayed with her friend 30 / 60 = .5 hours. So the total time was 1.5 + .5 = 2 hours.
So the answer is 2.

Question: There are 3 consecutive odd integers that have a sum of -147. What is the largest number?
Answer: Step-by-step reasoning process: Let N = smallest number. N + 2 = next number. N + 4 = largest number. N + (N + 2) + (N + 4) =  - 147. 3N + 6 =  - 147. 3N =  - 153. N =  - 51. The largest number is - 47.
So the answer is -47.

Question: Ivan has a bird feeder in his yard that holds two cups of birdseed. Every week, he has to refill the emptied feeder. Each cup of birdseed can feed fourteen birds, but Ivan is constantly chasing away a hungry squirrel that steals half a cup of birdseed from the feeder every week. How many birds does Ivan’s bird feeder feed weekly?
Answer:
Step-by-step reasoning process: The squirrel steals 1 / 2 cup of birdseed every week, so the birds eat 2 - 1 / 2 = 1 1 / 2 cups of birdseed. Each cup feeds 14 birds, so Ivan’s bird feeder feeds 14 * 1 1 / 2 = 21 birds weekly.
So the answer is 21.
