Two motorcyclists left the two cities to meet each other at the same time. The speed of the first rider is 56 km / h, the speed of the second is 13 km / h more. Find the distance between the cities, if after 4 hours the distance between the motorcyclists was 15 km.

1. Let’s find the speed of the second motorcyclist if it is known that his speed is 13 kilometers per hour more than the speed of the first motorcyclist.

56 + 13 = 69 kilometers per hour.

2. Determine the distance that a motorcyclist traveled in 4 hours at a speed of 56 kilometers per hour.

56 * 4 = 224 kilometers.

3. Find out how many kilometers in 4 hours a motorcyclist traveled at a speed of 69 kilometers per hour.

69 * 4 = 276 kilometers.

4. Find the distance between the cities from which motorcyclists left to meet each other.

224 + 276 + 15 = 515 kilometers.

Answer: The distance between cities is 515 kilometers.
