The car traveled 625 km, which was 3/5 of the way. How much is left for the car?

Let’s denote the entire path that the car must travel by the letter X.

In proportion, you need to compare the entire path of the car, as 5/5 of the entire path, and 625 km, as 3/5 of the entire path of the car.

We make up the proportion and determine the overall path of the car:

the whole path X – is 5/5 of the total path;

625 km – 3/5 of the total path;

X = 625 km * 5/3 = 1041.66 …

Let’s round up to 1041.67 km.

Let’s find the remaining distance that the car must travel:

1041.67 km – 625 km = 416.67 km.

Answer: 416.67 km left to drive.
