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

### Instruction:
 Stephen alifanya safari za pande zote 10 juu na chini ya mlima wenye urefu wa futi 40,000. Ikiwa alifikia 3/4 ya urefu wa mlima kwenye kila safari yake, hesabu umbali jumla aliokwenda.


### Response:
 Urefu wa mlima ni futi 40,000.
Ikiwa Stephen alifikia 3/4 ya urefu wa mlima kwenye kila safari yake, basi alifikia 3/4 * 40,000 = <<3/4*40000=30000>>30,000 futi kwenye kila safari.
Ikiwa alifanya safari za 10, basi alisafiri futi 30,000 * 10 = <<30000*10=300000>>300000 jumla.
