Час руху першого автомобіля можна знайти, розділивши відстань (345 км) на його швидкість (55 км/год), що дорівнює 6,27 год. Другий автомобіль їде за швидкістю, що становить 80% від швидкості першого, тому його швидкість складає 55 * 0,8 = 44 км/год. Тому час руху другого автомобіля також можна знайти, розділивши відстань (345 км) на його швидкість (44 км/год), отримуємо 7,84 год.
