Question
An emergency flare is shot vertically into the air with a speed of 60m/s. It's height h metres after t seconds is given by the equation h=−5(t−6)^2+180
To the nearest second, when does the flare reach its maximum height?

I know but this one is To the nearest second the other one was just the maximum height. Would the equation still be the same or would it be a different equation?

The vertex of the parabola is the top when t = 6 and h = 180
