Answer:
If it took the motorcycle 2 hours to cover 20km, then the average speed is 10km per hour.
Speed is equal to distance over time. So 20km divided by 2 hours is 10 km per hour.

Step-by-step explanation:
A polynomial is the sum of at least one term. For example, x^3+1 is a polynomial. A monomial is a polynomial with only one term, such as 2x^2.
A binomial is a polynomial with two terms, and a trinomial is one with three terms. The example you gave is a trinomial (which is also a polynomial).
Degree of a polynomial is the largest sum of variable powers in any term of the polynomial. So, for example, x^2 y has degree 3, and x^3+x^2 also has degree 3. A sixth degree polynomial would be x^6-2x+1, for example.
