Answer 2

Problem Analysis

Two cars are traveling towards each other from two different cities. The first car has a speed of 75 km/h, and the second car has a speed of 54 km/h. We need to find the distance between the cities if the cars meet after 6 hours.

Solution

To find the distance between the cities, we can use the formula:

Distance = Speed × Time

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

1. Distance traveled by the first car: - Speed of the first car = 75 km/h - Time = 6 hours - Distance = Speed × Time = 75 km/h × 6 hours = 450 km

2. Distance traveled by the second car: - Speed of the second car = 54 km/h - Time = 6 hours - Distance = Speed × Time = 54 km/h × 6 hours = 324 km

3. Total distance between the cities: - Total distance = Distance traveled by the first car + Distance traveled by the second car - Total distance = 450 km + 324 km = 774 km

Therefore, the distance between the cities is 774 km.

Answer

The distance between the two cities is 774 km.
