    C. y (x) = 10 x + 1

    Step-by-step explanation:

    Here, x represents the number of hours after 1 lap and y represents the total number of laps,

    Given,

    ' The total laps = 1 Lap + Total laps after 1 lap '

    Also, after 1 lap,

    The number of laps in one hour = 10,

    Thus, the number of laps in x hours = 10x

    Hence, we can write,

    y = 1 + 10x

    Since, y is dependent on x,

    So, y can be written as y (x),

    Therefore, the required equation is,

    y (x) = 1 + 10x

    Option C is correct.
