The distance travelled by a airplane departing from Toronto Pearson Airport is given implicitly by the equation

t³ 3 st 7 s³ = 0

Q8125476563 11FEB22

Where s is the distance in kilometres and t is time in seconds (s). Use implicit differentiation to calculate the velocity of the airplane when

s = 27

and

t = 14

seconds. Note: Enter your answer as a decimal rounded to four (4) decimal places without units. km/s
