When the car drove 0.2 ways, and then another 0.15 of the entire way, it turned out that he traveled

When the car drove 0.2 ways, and then another 0.15 of the entire way, it turned out that he traveled 18 km less than half of the way that it was necessary to travel. How many kilometers did the car have to travel?

The solution of the problem:

1) From the condition of the problem, we know that the car traveled 0.2 paths, and then another 0.15 of the entire path. Let’s write down and find how much the car has traveled:

0.2 + 0.15 = 0.35 – the distance traveled by the car.

2) It turned out that he traveled 18 kilometers less than half the way. Let’s find out what part of the total path is 18 kilometers:

0.5 – 0.35 = 0.15;

3) Now we find out how many kilometers the car had to drive:

18 / 0.15 = 120 km.

Answer to the problem: The car had to travel 120 kilometers.
