    This is the concept of algebra, let the number of miles jogged by Marcus be x, the number of miles jogged by Elena is (x+1) miles:

    Total number of miles jogged by the two individuals will be:

    x + (x+1) = 15

    2x+1=15

    putting like terms together we get:

    2x=15-1

    2x=14

    hence

    x=14/2 = 7miles

    therefore we conclude that Marcus jogged 7 miles while Elena jogged 8 miles.
