### Instruction:
Jamie is a firefighter. One day an emergency call comes in from Mrs. Thompson, an elderly woman whose cat can't get down a 20-foot tree. The last time Jamie rescued a cat, he got it down from a 6-foot tree and had to climb 12 rungs of his ladder. How many rungs does he have to climb this time to get the cat down from the tree?

### Response:
 Mara ya kwanza Jamie aliponyakua paka, alilazimika kupanda ngazi 12.
Wakati huu, anahitaji kupanda ngazi 12 * 20 / 6 = <<12*20/6=40>>40.
