O O OQuestion 6 (1 point) Numerical Response: Suppose that a Dash 8 airplane is travelling from Edmonton to Kelowna, a trip of about 600 km (by air), at a speed of 450km/h. Let w represent the speed of the wind, in kilometres per hour, where w is positive for a tailwind and negative for a headwind, and t represent the time, in hours, it takes to fly. The equation that represents t as a function of w is as follows 600 t w -+ 450 What is the non-permissible value for the function? W = (fill in the blank) (only numbers, period, negative sign allowed) Your answer should be numeral answers. Do Not show work.
