A line of best fit expresses the relationship between the points.
It does not go through all the points but goes through most of them and it is like a hardrawn curve
what is the question name
B. The wind is blowing at 20 m/s. The airplane is flying with the wind at 130 m/s.
From Physics we get that resultant velocity of an airplane is the sum of an absolute velocity and a relative velocity, that is:
- Wind velocity, measured in meters per second.
- Airplance velocity relative to wind, measured in meters per second.
- Airplane velocity, measured in meters per second.
If we assume that (The airplane flies with the wind), , then the resultant velocity of the airplane is:
Therefore, correct answer is B.
