Problem Analysis

We are given that two motorcyclists start simultaneously from two different cities and meet each other after 8 hours. We need to determine the distance between the cities given that one motorcyclist has a speed of 85 km/h and the other has a speed of 72 km/h.

Solution

To find the distance between the cities, we can use the formula: distance = speed * time.

Let's calculate the distance traveled by each motorcyclist and then find the total distance between the cities.

Motorcyclist 1: - Speed: 85 km/h - Time: 8 hours - Distance = 85 km/h * 8 hours = 680 km

Motorcyclist 2: - Speed: 72 km/h - Time: 8 hours - Distance = 72 km/h * 8 hours = 576 km

Total distance between the cities = Distance traveled by Motorcyclist 1 + Distance traveled by Motorcyclist 2 = 680 km + 576 km = 1256 km.

Therefore, the distance between the cities is 1256 km.

Answer

The distance between the two cities is 1256 km.
