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

### Instruction:
Tony has to run several errands in a day.  He needs to drive 10 miles to get groceries, 15 miles to get a haircut and 5 miles to go to a doctor's appointment.  How many miles will Tony have driven when he is halfway through driving around for his errands?

### Response:
 Kwanza, tunahitaji kupata jumla ya maili ambazo Tony atakuwa ameendesha kwa kuongeza 10+15+5=<<10+15+5=30>>30 maili kwa jumla.
Ili kujua sehemu ya katikati, tunagawanya tu jumla ya maili kwa 2, tukipata 30/2=<<15=15>>15 maili ambazo Tony ameendesha wakati anapokuwa katikati ya safari yake.
