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

### Instruction:
Pete walks backwards three times faster than Susan walks forwards, and Tracy does one-handed cartwheels twice as fast as Susan walks forwards.  But Pete can walk on his hands only one quarter the speed that Tracy can do cartwheels.  If Pete walks on his hands at 2 miles per hour, how fast can Pete walk backwards, in miles per hour?

### Response:
 Ikiwa Pete anatembea kwa mikono yake kwa kasi ya robo ya kasi ya Tracy anayeweza kufanya kuruka kwa mkono mmoja, hii inamaanisha Tracy anaweza kufanya kuruka kwa mkono mmoja kwa kasi ya maili 2 * 4 = 8 kwa saa.
Kwa kuwa Tracy anafanya kuruka kwa mkono mmoja mara mbili ya kasi ya Susan anavyotembea mbele, hii inamaanisha Susan anatembea kwa kasi ya 8/2 = <<8/2=4>>4 maili kwa saa.
Kwa kuwa Pete anatembea nyuma mara tatu zaidi ya kasi ya Susan anavyotembea mbele, hii inamaanisha Pete anatembea nyuma kwa kasi ya 4 * 3 = 12 maili kwa saa.
