Two cars drove out of two cities. the distance between them is 432 km, the speed of the first is 54 km / h, the speed of the second is 6 km / h less. what is the distance between them will be 3 hours?

1. Let’s determine what distance the first car will travel in three hours if it was moving at a speed of 54 kilometers per hour:

54 * 3 = 162 (km).

2. Find the speed of the second car if it is 6 kilometers per hour less than the speed of the first car:

54 – 6 = 48 (km / h).

3. Find out how many kilometers the second car will travel in three hours if it was traveling at a speed of 48 kilometers per hour:

48 * 3 = 144 (km).

4. Let’s determine how many kilometers the two cars have traveled:

162 + 144 = 306 (km).

5. Find the distance between the cars in three hours:

432 – 306 = 126 (km).

Answer: 126 kilometers.
