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

### Instruction:
A boy runs 1.5 km in 45 minutes. What is his speed in kilometers per hour?

### Response:
 Kwa kuwa saa moja ni sawa na dakika 60, basi dakika 45 ni sawa na 45/60 = <<45/60=0.75>>0.75 saa.
Kwa hiyo, kasi yake kwa kilomita kwa saa ni 1.5 km/0.75 saa = 2 kilomita kwa saa.
