Answer» ong>Answer: Time Taken = 2t² + 3t + 4 hr if Distance = 2t⁴ + 3t³ - 2t² - 9t - 12 km & Speed = t² - 3 km/hr Step-by-step explanation: Distance = 2t⁴ + 3t³ - 2t² - 9t - 12 km
Speed = t² - 3 km/hr
Time Taken = Distance / Speed
Time Taken = (2t⁴ + 3t³ - 2t² - 9t - 12)/ (t² - 3 )
2t² + 3t + 4
t² - 3 _|2t⁴ + 3t³ - 2t² - 9t - 12 |_
2t⁴ -6t²
