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

### Instruction:
 Kristine alisafiri kwenda Paris nchini Ufaransa kumtembelea rafiki yake. Katika safari hiyo, alisafiri kwa treni kwa kilomita 300 na kwa basi kwa nusu ya umbali huo. Baada ya kufika mjini, alilazimika kuchukua teksi na alisafiri kilomita tatu chini ya mara tatu ya umbali aliyesafiri kwa basi. Kristine alisafiri umbali gani jumla kufikia marudio yake?



### Response:
 Kristine alilazimika kusafiri kwa basi kilomita 300 / 2 = <<300/2=150>>150 km.
Kwa teksi, alilazimika kusafiri kilomita 150 / 3 = <<150/3=50>>50 km.
Jumla, alilazimika kusafiri kilomita 150 km + 50 km + 300 km = <<150+50+300=500>>500 km.
