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

### Instruction:
Jason has to drive home which is 120 miles away. If he drives at 60 miles per hour for 30 minutes, what speed does he have to average for the remainder of the drive to get there in exactly 1 hour 30 minutes?

### Response:
 Anaendesha kwa kasi ya maili 60 kwa saa * .5 saa = <<60*.5=30>>30 mwanzoni.
Anahitaji kuendesha maili 120 jumla - 30 maili alizoendesha = <<120-30=90>>90 zilizobaki.
Ana saa 1.5 - .5 saa = <<1.5-.5=1>>1 saa kuendesha umbali uliosalia.
Anapaswa kuendesha kwa wastani wa maili 90 kwa saa kuendesha maili 90 zilizobaki kwa saa 1.
