Amotorboat maintained a constant speed of 12 miles per hour relative to the water in going 45 miles upstream and then returning. the total time for the trip was 8.0 hours. use this information to find the speed of the current.

Speed of the current is 3 miles per hour.

Step-by-step explanation:

Since we have given that

Speed of motor boat = 12 miles per hour

Distance traveled upstream = 45 miles

Let the speed of the current be x

Total time taken by upstream and downstream = 8 hours

Relative speed for downstream is given by

Relative speed for upstream is given by

According to question, we have

Hence, Speed of the current is 3 miles per hour.

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.
