A cheetah looks up and sees a gazelle in the distance. The cheetah starts running towards the gazelle; when it catches the gazelle, it is running at the speed of 0.029km/s. If the acceleration of the cheetah is 4.14m/s2, how long does it take for the cheetah to catch the gazelle?

Get a new teacher, who does not use indefinite language: who is "it" in each instance? The world wonders.
I'm assuming the cheetah is running at 0.029 km/s (29m/s).
V = Vo + a*t = 29.
0 + 4.14*t = 29. t = ?.
V = Vo + a*t = 29.
0 + 4.14*t = 29. t = ?.
