Math Problem Statement
An electrician is working at the top of a ladder that is 15ft long and leaning against the wall when its bottom starts sliding at a rate of 1ft/s . Fortunately, a fellow worker catches it when the ladder’s bottom is 5ft from the wall. At what speed is the top of the ladder (along with the electrician) sliding down the wall at that instant? Round any intermediate calculations, if needed, to no less than six decimal places, and round your final answer to two decimal places.
