The displacement of a wave disturbance propagating in the positive x-direction is given by
`y =(1)/(1 + x^(2))`at `t = 0` and `y =(1)/(1 +(x - 1)^(2))` at `t =2s`
where, `x` and `y` are in meter. The shape of the wave disturbance does not change during the propagation. what is the velocity of the wave?

Explanation

To find the velocity of the wave given the displacement equations at two different times, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the given equations**:
- At \( t = 0 \):
\[
y = \frac{1}{1 + x^2}
