### Instruction:
Cary is 72 inches tall. Her younger brother Bill is half her height, and her younger sister Jan is 6 inches taller than Bill. How tall is Jan?

### Response:
 Kwanza tafuta urefu wa Bill kwa kugawa urefu wa Cary kwa 2: inchi 72 / 2 = <<72/2=36>>36 inchi
Kisha ongeza inchi sita ili kupata urefu wa Jan: inchi 36 + inchi 6 = <<36+6=42>>42 inchi
