Answer:
The answer is false or "impossible"
Step-by-step explanation:
Heres why I say this:
If the “average speed” in one hour make the car travel 50km, it means the speed could not be constant. So, it could be 90km/h during the first 30 minutes and 10km/h during the second 30 minutes. If this is the case, for example, in the next 12 minutes after the first hour, the car could be traveled 18km at 90km/h, completing 50 + 18 = 68km. The tricky word “average” makes it impossible to answer. Good try, but no cigar.
Answer:
cubic polynomial
Step-by-step explanation:
3 is highest exponent and 3 is cubic
there are more than 3 terms, so it's polynomial (poly=many)
Its nonlinear decreasing.
