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

### Instruction:
A mother planted a 16-inch tree on her son's first birthday.  On the day the tree was planted, the boy was 24 inches tall.  If the tree grows twice as fast as the boy does, how tall will the tree be by the time the boy is 36 inches tall?

### Response:
 Mtoto amekua kwa inchi 36 - 24 = <<36-24=12>>12 tangu mti ulipandwa.
Kwa kuwa mti unakua mara mbili kwa kasi ya mtoto, utakuwa umekua kwa inchi 12*2 = 24 wakati huu.
Hivyo, urefu wa mwisho wa mti ni 16 + 24 = <<16+24=40>>40 inchi.
