Round to the nearest tenth: h = s – 16t^2?
The height h (in feet) of an object that is dropped from the height of s feet is given by the formula h = s – 16t 2 , where t is the time the object has been falling. A 5 foot tall woman on a sidewalk looks directly overhead and sees a window washer drop a bottle from the 2 story. How long does she have to get out of the way? Round to the nearest tenth. (A story is 12 feet.)

s=19 (24 foot fall minus woman’s height)
19-16t^2
16t^2=19
t^2 =19/16 or 1.1875
t= 1.1 seconds
