Two gymnasts are running toward each other in a floor routine, and they plan to precisely time a flip to stay synchronized for the audience. The path of the gymnasts is parabolic and modeled by the following equations, where y is the height of the flip and x is the time in seconds
y = -(x - 5)2 + 3
y=-3(x-3)2 + x + 1
To make sure the flip is in unison, after how many seconds should the flip occur?
O2 seconds
O 3 seconds
O4 seconds
O 5 seconds
