In the case of the previous question, if the effect of the finite speed of sound were neglected, would \(h\) be larger or smaller? What percentage error would be made?

Previous question:

One wants to determine the depth hh of a well experimentally. For this purpose, you throw a stone into it, and you hear the thud at the bottom after a timetau equals 3.0 τ = 3.0 s. The speed of sound is worthv Subscript s Baseline equals 340 vs = 340 m/s. What is the valuehh?
