    Explanation:

    In this exercise, we know some facts:

    • Lin read for x minutes.
    • Elena read for more than that.

    The problem tells us nothing about the number of minutes Elena read more than Lin. However, let’s say Elena read one-third more than the number of minutes Lin read. Therefore:

    For Lin:

    Number \ of \ minutes \ Lin \ read=x

    For Elena:

    Number \ of \ minutes \ Elena \ read=x+\frac{1}{3}x \\ \\ Number \ of \ minutes \ Elena \ read=\frac{3x+x}{3} \\ \\ Number \ of \ minutes \ Elena \ read=\frac{4x}{3} \\ \\ Number \ of \ minutes \ Elena \ read=\frac{4x}{3} \\ \\ \\ By \ using \ decimals: \\ \\ Number \ of \ minutes \ Elena \ read \approx 1.33x
