Question

Пешеход прошел 70% намеченного пути и установил,что ему осталось пройти на 8,6 км меньше пройденного.Сколько всего км должен был пройти пешеход?

Answer 1

Пусть х - весь путь.

0,3х = 0,7х - 8,6

0,4х = 8,6

х = 21,5

Ответ: 21,5 км.

Answer 2

100%-70%=30%-осталось пройти

70%-30%=40%-разница в том, что прошел, и в том, что осталось пройти

8,6·100÷40=21,5(км)

Ответ. 21,5 км. 

Answer 3

Calculation of the Total Distance

To determine the total distance the pedestrian was supposed to walk, we can set up an equation based on the given information. Let's denote the total distance as D.

According to the problem statement, the pedestrian has walked 70% of the planned distance and found that the remaining distance is 8.6 km less than the distance already covered.

We can express this information in the following equation:

0.7D = D - 8.6

To solve for D, we can simplify the equation:

0.7D = D - 8.6

0.7D - D = -8.6

-0.3D = -8.6

Dividing both sides of the equation by -0.3, we get:

D = (-8.6) / (-0.3)

Simplifying further, we find:

D = 28.67 km

Therefore, the pedestrian was supposed to walk a total distance of 28.67 km.
