Q: Karina was born in 1970 and she is currently twice as old as her brother. If her current age is 40, in what year was her brother born?
A: If Karina is currently 40, and she is twice as old as her brother, then her brother is currently 40 / 2 = 20 years old. If Karina was born in 1970, then her brother was born in 1970 + 20 = 1990. The answer is 1990.
Question: Jane is looking at a tree. At the same time, the tree and Jane are casting shadows - the tree of 10 meters and Jane of 0.5 meters. Jane is 1.5 meters tall. How tall is the tree?
Answer: The shadow of Jane is 1.5 / 0.5 = 3 times smaller than her height. The height of the tree is therefore 3 times bigger than the shadow, so it's 3 * 10 = 30 meters tall. The answer is 30.
[Question]Jasmine gets off of work at 4:00 pm. After that, it will take her 30 minutes to commute home, 30 minutes to grocery shop, 10 minutes to pick up the dry cleaning, 20 minutes to pick up the dog from the groomers and 90 minutes to cook dinner when she returns home. What time will she eat dinner?
[Answer]Her errands include a 30 min commute and 30 min grocery shopping, 10 min for dry cleaning and 20 min to grab the dog for a total of 30 + 30 + 10 + 20 = 90 minutes. Her errands took 90 minutes and she has another 90 minutes of cooking for a total of 90 + 90 = 180 minutes of chores / errands. 60 minutes are in 1 hour and she has 180 minutes of work so that's 180 / 60 = 3 hours. She is off of work at 4:00 pm and has 3 hours of errands / chores so she won't be able to eat until 4 + 3 = 7:00 pm. The answer is 7.
