Question

What is the average speed of the car that cover a distance(2y cube - 7y squared 5y - 1)km in (2y - 1) hour?

Answer 1

Answer:

y²-3y+1

Step-by-step explanation:

Average speed = Total distance covered ÷ Total time taken

let average time be t

t = (2y³ - 7y² + 5y -1)÷ (2y-1)

= y² - 3y + 1
