How do u get the answer 9/2 onn this?

First, you have to convert hours to minutes which is multiply it by 60mins :

1 hr = 60 mins

3 hrs = 60×3

= 180 mins

Then, you have to divide it by 40 minutes to find the fraction :

180 ÷ 40 = 18/4

= 9/2

no oblique asymptote

step-by-step explanation:

to find the oblique asymptote of f(x)

here numerator has degree 1 and denomintor degree 2

degree of numerator < degree of denominator

hence there is no oblique asymptote

when the degree of the denominator > that of the numerator, we saw that the value in the denominator got so much bigger, so quickly,   giving us a horizontal asymptote of the x-axis. or we can write

f(x) = a polynomial of x + a proper fraction.

in this case only we have oblique asymptotes but not when numerator has less degree.
