The average speed of the two routes =2S÷(T? +T？ )。
The calculation method of average speed is: total distance/total time = average speed.
Total distance =2S, total time =T? +T？
Average speed = 2S÷? +T？ )。
Extended data:
Physically, speed has not only magnitude, but also direction. Mathematical calculation problems, only calculate speed, regardless of direction.
A particle moves from one position to another in space, and the length of the trajectory is called the distance traveled by the particle in this movement. Distance is a scalar, that is, a quantity without direction. Displacement and distance are two different physical quantities. In linear motion, the distance is the length of the linear trajectory; In curved motion, the distance is the length of the curve trajectory. When an object returns to its original place after a period of movement, the distance is not zero and the displacement is equal to zero.
The ratio of displacement to time of a variable-speed moving object is not constant. At this time, we can use a speed to roughly describe the moving speed of an object during this time. This speed is called the average speed.
Other calculation formulas
2×V？ ×V？ ?(V？ +V？ ) = average speed. (the average speed of the first half v? , the second half of the average speed v? )
In physics, speed is used to indicate the speed and direction of an object's motion. Velocity is numerically equal to the ratio of the displacement of the object movement to the time taken for the displacement to occur. The calculation formula of speed is V = Δ x/Δ t, and the unit of speed in the international system of units is meters per second.
