55. Finding the Depth of a Well. Two seconds after a chlorine tablet has been dropped into a well, a splash isheard. The speed of sound is 1100 ft/sec. How far is the
top of the well from the water?

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
