11-8=3 (ч) - время работы

6 км - расстояние между машинами

Скорость 2 машины - 30 км/ч

Скорость 1 машины -?

Составим уравнение:

Пусть x скорость 2 машины

(P. S. Формула скорости V= S/t, но мы выразим эту формулу)

x*3=6

x=6/3

x=2 (км/ч)- разница в скорости

(P. S. По рисунку видно что скорость 2 машины меньше)

30-2=28 (км/ч) - скорость 1 машины.

Ответ: скорость 1 машины 28 км/ч

(P. S. Жду спасибо и лучший ответ :) )
