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

### Instruction:
Candace is trying to decide whether to wear her old shoes or new high-tech shoes for a hike. The high-tech shoes will help Candace walk twice as fast, but they're not broken in yet, so she'll get 1 blister after every 2 hours she spends walking in them. Each blister slows Candance down by 2 miles per hour. If Candance walks 6 miles per hour in the old shoes and plans to hike for 4 hours, how many miles per hour can she go in the new shoes?

### Response:
 Kwa viatu vya teknolojia ya juu, Candace anaweza kutembea kwa kasi ya maili 6 * 2 = <<6*2=12>>12 kwa saa kwa masaa mawili ya kwanza.
Baada ya hapo, anapata kipele kimoja, hivyo kasi yake inapungua hadi 12 - 2 = <<12-2=10>>10 maili kwa saa kwa masaa mawili yajayo ya safari.
Kisha anapata kipele kingine, lakini masaa 2 + masaa 2 = <<2+2=4>>4, hivyo safari imeisha na hatujali kasi yake tena.
Tunavutiwa tu na masaa 4 ya kwanza ya safari, hivyo tunaweza kupuuza masaa mawili ya mwisho.
Kwa wastani wa masaa manne ya kwanza, Candace anatembea kwa kasi ya (12 maili kwa saa + 10 maili kwa saa)/2 = <<(12+10)/2=11>>11 maili kwa saa kwa viatu vya teknolojia ya juu.
