A boat can travel 16 km/h against the current.The same boat can travel 30 km/h with the current.find the rate of the boat in still water and the rate of the current.
Could someone help seams like an easy problem, but I am not getting there.Thank YU very much.

  • algebra -

    speed of boat in still water ---- x km/h
    speed of current ------- y km/h

    x+y = 30
    x-y = 16
    add them
    2x = 46
    x = 23
    then y = 7

    speed in still water is 23 km/h, speed of current is 7 km/h
