Below is an instruction that describes a task. Write a response that appropriately completes the request in Thai. Please answer in Thai.

### Instruction:
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?

### Response:
 การเดินทางครึ่งทางต้องใช้เวลา 1/2 x 20 x 30 = <<1/2*20*30=300>>300 กิโลเมตร
การเดินทาง 1/3 ทางที่เหลือต้องใช้เวลา 1/3 x 300 = <<1/3*300=100>>100 กิโลเมตร
ดังนั้น พายุลมพัดเรือไปทางทิศตะวันตกเป็นระยะทาง 300 - 100 = <<300-100=200>>200 กิโลเมตร
