    If \[\text{x}=\text{7 m}\] and \[\text{y}=\text{1}0\text{ m},\]then find d.

    A) \[\frac{30}{13}m\]

    B) \[\frac{50}{17}m\]

    C) \[\frac{70}{17}m\]

    D) \[\frac{90}{19}m\]

    Correct Answer: C

    Solution :

    Put \[x=7\] and \[y=10\] in equation (3), we get
    \[d=\frac{7\times 10}{7+10}=\frac{70}{17}m.\]
    So, option [c] is correct.
