    I do not see any axis lables. What is y? what is x?

    You probably meant the velocity in the x-direction.

    You calculated the time it takes a water drop exiting the soaker to drop throught a height of 1 meter. This is also the time it takes the same water drop to travel a horizontal distance of 10 meters (during the same time). So its horizontal speed is

    [tex]v_x = \frac{horizontal\ distance\ travelled}{time\ to\ travel\ this\ distance}[/tex]

    y is the direction of gravity.

    Just use the distance and the fact that the velocity in the x-direction remains constant to calculate the velocity given you know the time.
