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

### Instruction:
Anne is 2 times as tall as her sister while Bella is 3 times as tall as Anne. If Anne is 80cm tall, what is the height difference between Bella and Anne's sister?

### Response:
 Anne ni mara mbili urefu wa dada yake hivyo 2*(urefu wa dada yake) = 80 cm
Urefu wa dada yake = 80cm/2
Urefu wa dada yake = 40 cm
Bella ni mara tatu urefu wa Anne hivyo urefu wa Bella ni 3*80 cm = <<3*80=240>>240 cm
Tofauti ya urefu kati ya Bella na dada yake Anne = 240-40 = <<240-40=200>>200 cm
