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

### Instruction:
James takes up dancing for fitness.  He loses twice as many calories per hour as he did when he was walking.  He dances twice a day for .5 hours each time and he does this 4 times a week.  He burned 300 calories an hour walking.  How many calories does he lose a week from dancing?

### Response:
 Anapoteza kalori 2*300=<<2*300=600>>600 kwa saa.
Anacheza kwa muda wa saa 0.5*2=<<0.5*2=1>>1 kwa siku.
Hivyo anapoteza kalori 600*1=<<600=600>>600 kwa siku.
Hivyo anapoteza kalori 600*4=<<600*4=2400>>2400 kwa wiki.
