    Speed of the boat = u

    speed of the current = v

    in downstream,

    u - v = 105/5

    u - v = 21

    in upstream

    u + v = 105/7

    u + v = 15

    add both equations

    2u = 36

    u = 18

    v = - 3

    so

    speed of the boat = 18 km/h

    speed of the current = 3 km/h
