Answer 2

Problem Analysis

Two cars are traveling in opposite directions from a city. The speed of one car is 70 km/h, and the speed of the other car is 80 km/h. We need to find the distance between the two cars after 3 hours.

Solution

To find the distance between the two cars after 3 hours, we need to calculate the total distance traveled by each car.

Let's calculate the distance traveled by the first car: - Speed of the first car = 70 km/h - Time traveled by the first car = 3 hours - Distance traveled by the first car = Speed * Time = 70 km/h * 3 hours = 210 km

Now, let's calculate the distance traveled by the second car: - Speed of the second car = 80 km/h - Time traveled by the second car = 3 hours - Distance traveled by the second car = Speed * Time = 80 km/h * 3 hours = 240 km

The distance between the two cars after 3 hours is the sum of the distances traveled by each car: - Distance between the two cars = Distance traveled by the first car + Distance traveled by the second car = 210 km + 240 km = 450 km

Therefore, the distance between the two cars after 3 hours is 450 km.

Answer

The distance between the two cars after 3 hours will be 450 km.
