    Let 7x be the first length

    Let 8x be the second length

    The first length is 273:

    7x = 273

    x = 273/7

    x = 39

    Now calculate the second length:

    8x = 8(39) = 312

    Answer:

    312 m

    P.S. If you want a shortcut, multiply 273 by 8/7.

    The 2nd length is 312 m because 273/312 is a ratio of 7/8 and (273+312)/15 = 39

    So: 7*39 = 273 and 8*39 = 312
