Katie is determining the time it will take to travel 405 miles by train. the train travels 90 miles per hour. a)1.5 hours b)4.5 hours c) 4 hours d) 3.8 hours

distance = rate * time

405 miles = 90 miles/hour * time

divide  each side by 90

405/90 = time

4.5 hours = time

Choice B

.25

step-by-step explanation:

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.
