Problem 116. Justo has a twelve-foot ladder leaning against a vertical wall as shown below. Mr. Hipsickles scampers up the ladder, causing the base of the ladder to slide away from the wall. Let x represent the horizontal distance, measured in feet, between the base of the ladder and the wall; and let y represent the vertical distance, measured in feet, between the top of the ladder and the ground. Let t represent the number of seconds passed since the ladder began to slide. When the base of the ladder is six feet from the wall, suppose we know that d= 7.6 feet per second. What is the corresponding value of ? dt

Problem 116. Justo has a twelve-foot ladder leaning against a vertical wall as shown
below. Mr. Hipsickles scampers up the ladder, causing the base of the ladder to slide
away from the wall. Let x represent the horizontal distance, measured in feet, between
the base of the ladder and the wall; and let y represent the vertical distance, measured
in feet, between the top of the ladder and the ground. Let t represent the number of
seconds passed since the ladder began to slide.
When the base of the ladder is six feet from the wall, suppose
we know that d = 7.6 feet per second. What is the
corresponding value of ?
