Two window washers start at the heights shown. One is rising, the other is descending. How long does it take for the two window washers to reach the same height? Explain. 21 ft high rising 8 in./s 50 ft high descending 11 in./s After t seconds, the height of the rising window washer is exactly feet, and the height of the descending window washer is exactly feet. Setting these expressions equal to each other and solving for t yields the exact value t=. Rounding to one decimal place, the window washers reach the same height after about seconds. (Simplify your answers.)
