Time to reach highest point after 3sec = $\frac{7-3}{2}=2sec.$

Time to reach highest point from ground = 3+2 = 5sec.

As upward and downward motion are symmetric [Time taken from A$\to$B is same as time taken from B$\to$C]

So, time to reach highest point is 5s. Same time is required to reach from B to ground.

For downward motion,
