Answer:

6.2 seconds

Step-by-step explanation:

To translate into math, the question is asking you "for what approximate t value does h = 0?" In order to solve, you can plug in 0 for h and solve for t.

0 = -16t^2 + 620

-620 = -16t^2

620 = 16t^2

38.75 = t^2

[tex]\sqrt{38.75}[/tex] = t

6.2 ~~ t (rounding to the nearest tenth)
