2 вариант
70 км - 14%
? км - 86%
(70*86)/100=430 км - осталось проехать

Answer 2

1) 70:14%*100%=500 (км)-весь путь;
2) 500-70=430 (км)-осталось проехать;

Answer 3

Calculation of Remaining Distance

To calculate the remaining distance the train has to travel, we can use the information provided: the train has already traveled 70 km, which represents 14% of the total distance.

To find the total distance, we can set up a proportion:

70 km / x = 14% / 100%

To solve for x, we can cross-multiply and then divide:

70 km * 100% = 14% * x

7000 km = 14% * x

To find x, we can divide both sides of the equation by 14%:

x = 7000 km / 14%

Now we can calculate the remaining distance:

x = 7000 km / 0.14

Using a calculator, we find that x is equal to 50,000 km.

Therefore, the train still has 50,000 km left to travel.
