Ответ:

8км

Пошаговое объяснение:

1) 32км / 100 * 37.5 = 12км (пройшов за 1 день)

2) 32км - 12км = 20км ( решта)

3) 20км / 5 * 3 = 12км ( 3/5 решти)

4) 20км - 12км = 8км ( пройшов 3 дня )

Ответ:

Нехай x - відстань, яку турист пройшов третього дня.

Перший день: 0.375х

Другий день:

 \frac{3}{5} (x - 0.375x) =  \frac{3}{5}  \times 0.625x

Третій день: х

За три дні в сумі:

0.375x +  \frac{3}{5}  \times 0.625x + x = 32

Розв'язавши це рівняння, знайдемо значення x для третього дня.
