    74 minutes

    Simple Solution:

    If you use common sense you can just look at the ratios and find that 14 is 7 twice. You apply the same pattern to 37 and you get 74.

    Explanation:

    Convert the word problem into proportional relationships (Ratios). You should get (7/14) and (37/?). Divide 37 by 7 (Use a calculator for this). Multiply the quotient by 14 to get a final answer of 74.
