Step-by-step explanation:

Very easy question. Just represent it properly and you will answer in 30 seconds.

A——1 Tank——6 hrs. (read as: A can fill 1 tank in 6 hours).

So, A——(1/6) Tank——1 Hr

B——1 tank——12 hrs.(keep in mind it empties, so there will be a minus sign).

So, B——(1/12) Tank——1 Hr

A+B——(1/6)-(1/12) Tank——1 Hr

A+B——(1/12) Tank——1 Hr

A+B——1 Tank—— 12Hrs
