In the first hour, the car drove 50 km, which was 25% of the entire route.

In the first hour, the car drove 50 km, which was 25% of the entire route. In the second hour, she covered 30% of the way. How far is she left to travel?

Let’s find how many kilometers are in 1% of the way:
1% = 50/25 = 2 km.
Let’s find the percentage of the car traveled in the first 2 hours of the journey:
25 + 30 = 55%.
The rest of the path is:
100 – 55 = 45%.
Let’s find how much it will be in kilometers:
45 * 2 = 90 km.
Answer: after 2 hours of travel, the car has 90 kilometers left to drive.
