Answer the following question.
On the first day of the journey, the Skipper sailed his ship halfway to the destination by traveling due east for 20 hours at a speed of 30 kilometers per hour, and then turned the ship's engines off to let them cool down. But while the engines were off, a wind storm blew his vessel backward in a westward direction. After the storm, the Skipper used his GPS device to determine the new location of the ship, and he discovered that he was only one-third of the way to his destination. How many kilometers had the ship been blown in a westward direction by the storm?
Step-by-step reasoning process: Traveling 20 hours due east at 30 kilometers per hour, the ship sailed 20 * 30 = 600 kilometers the first day. If half the distance to the destination is 600 kilometers, then 2 * 600 = 1200 kilometers is the total distance from start to destination. One - third of the distance from start to destination is 1 / 3 * 1200 = 400 kilometers. Thus, the wind storm blew the ship in a westward direction for 600 - 400 = 200 kilometers.
The answer is 200.

Answer the following question.
Ruby is taking dance lessons. They cost $75 for 10 classes in one pack. She can add additional classes at the price of 1/3 more than the average price of a class on the lesson in the pack. if she takes 13 total classes, how much does she pay?
Step-by-step reasoning process: The classes in the pack cost $7.5 each because 75 / 10 = 7.5. An additional class costs $10 because 7.5 x (1 + (1 / 3)) = 10. She buys 3 extra classes because 13 - 10 = 3. Her three additional classes cost $30 because 3 x 10 = 30. Her total cost is $105 because 75 + 30 = 105.
The answer is 105.

Answer the following question.
Lavinia’s daughter is 10 years younger than Katie’s daughter. Lavinia’s son is 2 times the age of Katie’s daughter. If Katie’s daughter is 12 years old, how many years older is Lavinia’s son than Lavinia’s daughter?
Step-by-step reasoning process: Lavinia’s daughter is 12 - 10 = 2 years old. Lavinia’s son is 12 * 2 = 24 years old. Lavinia’s son is 24 - 2 = 22 years older than Lavinia’s daughter.
The answer is 22.

Answer the following question.
A pole is 20 meters long. It got cut in a way that left it 30% shorter. How long is the pole?
Step-by-step reasoning process: The cut - away part of the pole is 30 / 100 * 20 = 6 meters long. So the pole is left at the length of 20 - 6 = 14 meters.
The answer is 14.
