Answer:
Average speed in km / h = 2.7 km/h
Step-by-step explanation:
Given:
Total distance = 54,000 m
Total time = 72,000 sec
Find:
Average speed in km / h
Computation:
Average speed = Distance / Time
Average speed = 54,000 / 72,000
Average speed = 0.75 m/s
1 m/s = 3.6 km/h
So,
Average speed in km / h = 0.75 x 3.6
Average speed in km / h = 2.7 km/h

<u>The term that describe a fraction that has a polynomial in its numerator and its denominator is </u><u>Rational Expression</u>
<h2>Explanation:</h2>
The term that describes a fraction ,it has a variable or variable expression in its numerator, its denominator, or both is called a rational fraction. It is occur when both the numerator and the denominator are polynomials.In the below example xy are polynomials.
For example a rational expression given by 25x²y²/ 6xy can be simplified into (25 × x × x× y× y)/ 6× x× y
So
=25xy /6
1 is the value of a ther is always a imaginary 1 infront of a letter
sin 45 = opp/hyp
sin 45 = 4 / y
y = 4/sin 45
y = 4 /((sqrt2)/2)=4* sqrt(2)
tan 45 =opp/adj
tan 45 = 4/(x-3)
1 = 4/(x-3)
x-3 = 4
x=7
