Step by step of this one?

The explanation pretty much says it all. Since we are calculating the horizontal distance,

Δx = v1 * Δt + 1/2 a * (Δt)^2

We already calculated Δt in the previous problem as 1.2s. And since there is no horizontal force acting on the student, horizontal acceleration or a = 0. So, we are left with Δx = v1 * Δt = 5m/s * 1.2s = 6m.
