Ответ:Для того, щоб визначити відстань, яку проїхав автомобіль за три години, необхідно спочатку визначити загальну відстань, яку він мав проїхати. На першу годину він проїхав 4/9 від загальної відстані, тому загальна відстань складає 9/4=2,25 рази більше, ніж відстань, яку він проїхав за першу годину. Це означає, що загальна відстань складає 60 км * 2,25 = 135 км.

На другу годину він проїхав 60% того, що залишилось, тому він проїхав 60/100 * (135 - 60) = 36 км.

Загалом за три години він проїхав 60 + 36 + 60 = 156 км.
