    56 minutes

    Step-by-step explanation:

    14 people painting 14 walls is simply double (x2) 7 people painting seven walls.

    We know this because 7 x 2 = 14

    So, we will have to double the amount of time it takes them to paint.

    28 x 2 = 56

    It will take 56 minutes for 14 people to paint 7 walls!
