Ответ:

102 км/ч

Пошаговое объяснение:

Можно решать по разному.

1 способ: Грузовик за 2 часа проехал 62*2=124 км

Автомобиль проехал за 2 часа  328-124=204 км

Значит скорость автомобиля  204:2=102 км/ч.

2 способ. Пусть скорость автомобиля х.

Скорость сближения грузовика и автомобиля 62+х

(62+х)*2=328

62+х=164

х=102 км/ч
