2. Every morning Abhay goes for Jogging in a park.
(a) Find the time taken by him to cover a distance of (2t^4 + 3t^3– 2t^2- 9t - 12) km at
the speed of (t^2– 3) km/hr.
(b) Write the importance of physical exercises like jogging, walking, etc.
Answers
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
