The distance between cities A and B is 288 km. From city A to city B, a car drove out at a speed of 72 km / h. Simultaneously with the car, a cyclist left city B for city A. How long does it take for a car to travel between cities? How long does it take for a cyclist?

1. Let’s find what distance the car has covered in 3 hours.

3 * 72 = 216 kilometers.

2. Let’s calculate the path of the cyclist.

288 – 216 = 72 kilometers.

3. Determine with what speed per hour he was driving, if it is known that he covered 72 kilometers in 3 hours.

72/3 = 24 kilometers.

4. Let’s calculate how many hours the car spent on the passage of 288 kilometers.

288/72 = 4 hours.

5. Find how long it took the cyclist to cover the same distance.

288/24 = 12 hours.

Answer: A car will cover the distance between cities in 4 hours, and a cyclist in 12 hours.
