Two cars drove out simultaneously towards each other from two cities, the distance between which is 600 km

Two cars drove out simultaneously towards each other from two cities, the distance between which is 600 km, and met in 4 hours. Determine the speed of each car if one was moving faster than the other by 12 km / h.

1. Let’s calculate how many more kilometers a car has traveled, the speed of which is 12 kilometers per hour more.

12 * 4 = 48 kilometers.

2. Find out the distance that the cars have traveled equally.

600 – 48 = 552 kilometers.

3. Let us determine at what speed the first car drove per hour, if it is known that it was on the way for 4 hours.

552/2/4 = 69 kilometers.

4. Find out the speed of the second car if it is known that it traveled 48 kilometers more than the first car.

(552/2 + 48) / 4 = 81 kilometers.

Answer: The speed of the first car was 69 kilometers per hour, and the speed of the second car was 81 kilometers per hour.
