Відповідь:

На подолання відстані у 560 км автомобілю знадобиться 8 годин.

Покрокове пояснення:

Швидкість автомобіля дорівнює:

560 / 7 = 80 км/год.

Якщо автомобіль зменьшить свою швидкість на 10 км/год, то його швидкість стане:

80 - 10 = 70 км/год.

На подолання відстані у 560 км автомобілю знадобиться:

560 / 70 = 8 годин.
