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

### 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:
 Kusafiri masaa 20 kuelekea mashariki kwa kasi ya kilomita 30 kwa saa, meli ilisafiri kilomita 20*30=<<20*30=600>>600 siku ya kwanza.
Ikiwa nusu ya umbali kuelekea marudio ni kilomita 600, basi jumla ya kilomita kutoka mwanzo hadi marudio ni 2*600=<<2*600=1200>>1200.
Hivyo, baada ya dhoruba ya upepo, meli ilikuwa umbali wa 1/3*1200=<<1/3*1200=400>>400 kilomita kutoka marudio yake.
Ikiwa meli ilikuwa kilomita 600 mashariki ya marudio wakati dhoruba ya upepo ilipeperusha meli kuelekea magharibi, basi dhoruba ya upepo ilipeperusha meli kwa umbali wa 600-400=<<600-400=200>>200 kilomita kuelekea magharibi.
