When solving mathematical problems, students have a large number of questions. "How to find the rate of convergence?" - one of them.
The speed of movement is the distance that objects approach each other per unit of time. The unit of measurement is km / h, m / s, etc. With a uniform motion of objects with different speeds, the distance between these objects either increases or decreases by the same number of units.
In order to calculate the motion in different directions, it is necessary to use the formula: approach speed = V1 + V2, and when moving in one direction - approach speed = V1 - V2. When solving problems, do not confuse the speed of approach with the “total speed”, which is calculated by the sum of the entire speeds.
Suppose two cyclists are moving towards each other. The speed of the first - 16 km / h, and the second - 20 km / h. How fast does the distance between them change? Substituting our data into the formula V = 16 + 20, we learn that the approach speed in this case is 36 km / h.
If two turtles participate in the races, one of which moves at a speed of 3 km / h and the other 1 km / h, the rendezvous speed will turn out to be 2 km / h based on the formula V = V1 - V2.
