ответ:

отдел +;

использует приём из "", вывод из "";

пер

  n, сумма, сч, скор, макс: цел;

указ

  сумма : = 0;

  макс : = 0;

  вывод.цепь("введите число автомобилей: ");

  n : = приём.число();

  если n < 1 и n > 30 то вывод.цепь("^ошибка.") иначе

    вывод.цепь("^введите скорости: ^");

    от сч : = 1 до n вып

      скор : = приём.число();

      если n < 1 и n > 300 то вывод.цепь("^ошибка."); стоп(0) кон;

      увеличить(сумма, скор);

      если скор > макс то макс : = скор кон;

      вывод.цепь(" ")
