Ответ:

Пусть скорость первого автомобиля равна х км / ч, тогда скорость второго автомобиля - (х + 10) км / ч. За 2,5 ч первый автомобиль проехал 2,5л: km, а второй - 2,5 (л: + 10) км. Согласно условию задачи составляем уравнение:

2,5x + 2,5 (x + 10) = 325;

2,5x + 2,5л: + 25 = 325;

5x = 300;

x = 60.

Следовательно, скорость первого автомобиля равна 60 км / ч, а скорость второго - 60 + 10 = 70 (км / ч).

Ответ. 60 км / ч, 70 км /
