Whats the question

Answer 2

A football is kicked into the air from an initial height of 3 feet. The height, in feet, of the football above the ground is given by s(t) = -16t^2 + 35t + 3. Where t is the time in seconds and t >= 0. Which is the closest to the time when the football will be 20 feet above the ground?

Answer 3

1) 2.72 seconds
2) 0.73 seconds or 1.46 seconds
3) 0.53 seconds
4) 0.53 seconds or 2.72 seconds

Answer 4

I think it is 3) because when I plugged in 0.53 for t it was closest to 20.
