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

### Instruction:
Walter fell from the eighth platform of some scaffolding and fell past David after falling 4 meters. If he fell for an additional three more times that depth before hitting the ground, and the platforms are evenly spaced out in height, what platform was David on?

### Response:
 Walter alidondoka mita 4 na mara tatu zaidi ya kina hicho ambacho ni 3*4 = 12 mita.
Alidondoka kwa jumla ya mita 4+12 = <<4+12=16>>16.
Jukwaa la nane lina urefu wa mita 16 na majukwaa yamepangwa sawasawa hivyo kila jukwaa lina urefu wa mita 16/8 = <<16/8=2>>2.
David alikuwa amepoziwa mita 4 chini ya kiwango cha mita 16 ambacho ni mita 16-4 = <<16-4=12>>12,
Hivyo David alikuwa amepoziwa mita 12 na majukwaa yana urefu wa mita 2 hivyo alikuwa amepoziwa mita 12/2 = <<12/2=6>>6 ambayo ni jukwaa la sita.
