Two cyclists set out from two cities towards each other. One cyclist, moving at a speed of 18 km / h, drove 54 km to the meeting. The speed of the second cyclist was 15 km / h. What is the distance between cities.

We will solve this task in steps and explain each of them in detail.

1) 54:18 = 3 hours – in such a first cyclist covered a distance of 54 kilometers at a speed of 18 kilometers per hour;

2) 3 * 15 = 45 kilometers – the distance traveled by the second cyclist in 3 hours of his movement at a speed of 15 kilometers per hour;

3) 45 + 54 = 99 kilometers – the distance between cities.

Answer: 99 kilometers.
