Anna throws a ball horizontally off her apartment balcony at a speed of 6.0 meters/second. If the ball falls 10 meters from the balcony to the base of the apartment, calculate how long it takes the ball to reach the base.
Choices:
-0.6 seconds
-1.7 seconds
-10 seconds
-60 seconds

I was thinking it's 60 seconds, because I multiplied 6 by 10, but I don't trust myself..
