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

### Instruction:
Stephen made 10 round trips up and down a 40,000 foot tall mountain. If he reached 3/4 of the mountain's height on each of his trips, calculate the total distance he covered.

### 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.
