Question

what is the average speed of a car that covers a distance of 2y^3-7y^2+5y-1 km in 2y-1?

Answer 1

Answer:

$y^{2}-3y+1$

Step-by-step explanation:

Speed(v)=$\frac{Distance(s)}{time(t)}$

Distance travelled by such a object in 2y-1 time is $2y^{3}-7y^{2}+5y-1km$

∴v=$\frac{2y^{3}-7y^{2}+5y-1km}{2y-1}$

by polynomial division,

(the sum is attached to this answer as png)

v=$y^{2}-3y+1$

∴ the average speed of such a car is $y^{2}-3y+1$
