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

### Instruction:
Luke is planning a trip to London and wants to see how long it will take him to travel there. He decides that he will take a bus to the town center, walk for 15 minutes to the train center, wait twice this long for the train to arrive, and then take the 6-hour train ride to London. If Luke’s entire trip takes him 8 hours, how many minutes does his bus ride take?

### Response:
 Kwa kuondoa muda wa safari ya treni kutoka kwenye safari yake, inaonyesha kwamba safari yake ya kufika kwenye treni ilimchukua masaa 8 - 6 = <<8-6=2>>2 masaa.
Kubadilisha muda huu kuwa dakika inaonyesha kwamba kufika kwenye treni kulimchukua masaa 2 * 60 dakika/saa = <<2*60=120>>120 dakika.
Kusubiri treni ifike kulichukua mara mbili ya muda wa kutembea kwake, hivyo dakika 15 * 2 = <<15*2=30>>30 dakika.
Hii inamaanisha kwamba safari yake ya basi ilichukua dakika 120 - 15 dakika - 30 dakika = <<120-15-30=75>>75 dakika.
