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

### Instruction:
Javier is an Olympic javelin thrower.  In the last Olympics, he threw the javelin three times.  The first throw, he threw the javelin twice as far as he threw the javelin on his second throw, but only half as far as he threw it the third throw.  If the sum of all three throws was 1050 meters, then how far, in meters, did he throw the javelin on his first throw?

### Response:
 Hebu x iwe umbali aliourusha mkuki katika rukia yake ya kwanza.
Hivyo, jumla ya rukia zake tatu ni x+0.5x+2x=1050 mita.
Hivyo, jumla ya rukia zake tatu ni 3.5x=1050.
Hivyo, umbali aliourusha mkuki katika rukia yake ya kwanza ni x=1050/3.5=<<1050/3.5=300>>300 mita.
