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

### Instruction:
Bob's school track is 400 meters. If Bob ran the first lap in 70 seconds, the second and third lap in 85 seconds each, what was his average speed in (m/s) for his entire run?

### Response:
 Ikiwa kila mzunguko una urefu wa mita 400, basi mizunguko 3 itakuwa na umbali jumla wa mita 400*3 = <<400*3=1200>>1200.
Jumla ya muda aliokimbia ni 70 kwenye mzunguko wa kwanza + 85 kwenye mzunguko wa pili na 85 kwenye mzunguko wa tatu, hivyo jumla ya muda wa kukimbia ulikuwa = 70+85+85 = <<70+85+85=240>>240 sekunde.
Kasi yake ya wastani inapimwa kwa umbali jumla aliokimbia (1200) uliogawanywa na muda jumla uliotumika (240) au 1200/240 = <<1200/240=5>>5 m/s.
