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

### Instruction:
Ezekiel hikes as a hobby. This past summer, he did a challenging three-day hike across 50 kilometers of wilderness. The first day, he covered 10 kilometers of steep mountainside. The second day was flatter and he was able to cover half the full hike distance. How many kilometers did he have to hike on the third day to finish the hike?

### Response:
 Baada ya siku ya kwanza, Ezekiel alipanda kilomita 10 * 1 = <<10*1=10>>10.
Siku ya pili, alipanda kilomita 50 / 2 = <<50/2=25>>25.
Baada ya siku mbili, alikuwa amepanda kilomita 10 + 25 = <<10+25=35>>35.
Ili kukamilisha safari, Ezekiel alikuwa na kilomita 50 - 35 = <<50-35=15>>15 zilizobaki.
