3. Evaluate the plot of seismic reflection data below (time^2 [ms^2 x10³] vs. distance^2 [m^2]). The values

for the 1st layer are provided. For the 2nd layer, use the best fit line equation shown (y = mx + b) providing

the intercept and slope to determine the velocity, Vrms of the 2nd layer along with foz (in sec). Use the

values to determine V₂ in (m/s) with the corresponding h, and h₂, and depth to the 2nd layer.
