Answer 1

1) 80-65=15км/ч скорость отдаления
2)80+65=145 км/чск орость сближения

Answer 2

Calculation of the Closing or Separation Speed

To calculate the closing or separation speed between two objects moving in opposite directions, we can find the difference between their speeds. In this case, we have two trains moving in opposite directions, with speeds of 65 km/h and 80 km/h.

The closing speed is the sum of their speeds, while the separation speed is the difference between their speeds.

Let's calculate the closing and separation speeds:

1. Closing Speed: - Train A: 65 km/h - Train B: 80 km/h - Closing Speed = Train A's speed + Train B's speed = 65 km/h + 80 km/h = 145 km/h

2. Separation Speed: - Train A: 65 km/h - Train B: 80 km/h - Separation Speed = Train B's speed - Train A's speed = 80 km/h - 65 km/h = 15 km/h

Therefore, the closing speed between the two trains is 145 km/h, and the separation speed is 15 km/h.
